Let's Encrypt live status and outage tracking
Let's Encrypt is a certificate authority that issues free TLS certificates, so your site can use HTTPS without buying a certificate. You may search for "is Let's Encrypt down right now" when issuance or renewal fails, since a short service interruption can affect new certificates while existing ones keep working.
Currently, based on our real-time global monitoring network, the status of Let's Encrypt is operational. There are currently no widespread network anomalies detected. If you are one of the few users currently struggling with an alleged Let's Encrypt outage, it is almost certainly an isolated incident affecting only your specific connection route or an outdated application client.
What a Let's Encrypt outage affects
A Let's Encrypt outage can stop new certificate issuance and leave renewal jobs waiting. Your site may keep serving its current certificate, but expired certificates can trigger browser warnings or failed connections; the last 24 hours show {UPTIME} uptime across {REPORTS} reports.
When the timeline chart illuminates red or yellow, it means a sizable portion of the player or user base is getting hit by these exact bugs. isitdownrightnow.app actively sifts through the noise to confirm when a real Let's Encrypt outage is happening rather than a localized glitch.
Recent Let's Encrypt outage reports and server status
Transparency into historical performance is key. Over the past 24 hours alone, our advanced tracking systems have recorded a total of 0 unique problem reports from users experiencing connectivity or functional issues with Let's Encrypt. Currently, the service has maintained a 100.00% uptime rating over this recent 24-hour tracking window.
Over the past day, we have not registered a single severe outage spike. The flatlined green bars on the chart confirm a stable, reliable 24-hour window with zero widespread disruptions.
Fixing Let's Encrypt when it is not working
Still can't connect even though the servers are green? The Let's Encrypt lag is likely on your end. Run through this quick checklist to get back online:
- Check the live Let's Encrypt status: The live Let's Encrypt server status is {STATUS}; uptime is {UPTIME}% over the past 24 hours, with {REPORTS} outage reports and the last outage {LASTDOWN} ago. That answers "is Let's Encrypt down" and "is Let's Encrypt down right now?"
- Retry a failed Certbot renewal: If Let's Encrypt not working today affects Certbot, run certbot renew --dry-run and read the challenge error before trying again; a wrong webroot or blocked port 80 can stop validation. Search "Let's Encrypt outage today 2026" if several certificates fail at once.
- Check DNS and port 443: For a Let's Encrypt down detector check, run nslookup acme-v02.api.letsencrypt.org in a terminal, then test the request from a phone hotspot; a stale resolver or blocked outbound port 443 can affect validation. This check shows the Let's Encrypt network status and whether Let's Encrypt is working from your connection.
How to Fix & Check if Let's Encrypt Is Down on Windows, Mac, Android & iOS
Let's Encrypt on Windows
Fix: Fix Let's Encrypt certificate errors on Windows by running Windows Update to update your root certificates, or manually import the ISRG Root X1 certificate into the Windows Certificate Manager.
Check: To check if Let's Encrypt is down on Windows, visit their official status page or test if you get SSL connection errors on websites that use Let's Encrypt certificates.
ping letsencrypt.org
Test whether Let's Encrypt's servers reply nslookup letsencrypt.org
Check that Let's Encrypt's DNS resolves tracert letsencrypt.org
Trace where the connection drops ipconfig /flushdns
Clear the DNS cache, then reload Let's Encrypt on Mac
Fix: Resolve Let's Encrypt trust issues on macOS by updating your operating system or manually importing and setting the ISRG Root X1 certificate to 'Always Trust' in Keychain Access.
Check: Verify if Let's Encrypt is down on a Mac by checking the official Let's Encrypt status page or inspecting certificate details in Safari or Keychain Access.
ping -c 4 letsencrypt.org
Test whether Let's Encrypt's servers reply nslookup letsencrypt.org
Check that Let's Encrypt's DNS resolves traceroute letsencrypt.org
Trace where the connection drops sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
Flush the macOS DNS cache, then reload Let's Encrypt on Android
Fix: Fix Let's Encrypt certificate issues on Android by installing the latest system updates, or use the Firefox browser which uses its own updated root certificate store.
Check: Determine if Let's Encrypt is down on Android by checking if multiple secure websites fail to load with SSL warnings, or by visiting the Let's Encrypt status site.
Let's Encrypt on iPhone / iPad
Fix: Fix Let's Encrypt connection errors on iOS by updating your iPhone or iPad to the latest iOS version to refresh the system's trusted root certificates.
Check: Check if Let's Encrypt is down on iOS by checking if Safari displays 'Certificate Not Trusted' warnings on Let's Encrypt-secured websites.
How we monitor Let's Encrypt status
Unlike internal corporate status pages, which are notoriously slow to update and often hide the true extent of ongoing failures, isitdownrightnow.app relies directly on the community. By crowdsourcing live problem reports submitted by real users worldwide, we can detect a massive Let's Encrypt crash literally within seconds of it beginning.
By comparing the live influx of complaints to a standard 7-day algorithmic baseline, our anomaly detection engine spots real outages instantly. When the reporting volume shatters the threshold, the alert goes out. This ensures that when you look for a Let's Encrypt down detector, you are always getting mathematically proven, community-verified outage maps.
quiz Frequently Asked Questions
help Is Let's Encrypt down right now?
At the time of this check, Let's Encrypt is {STATUS}, with {REPORTS} outage reports in the last 24 hours and a 24 hour uptime reading of {UPTIME}%. That answers "is Let's Encrypt down right now" from the latest crowd-sourced reports, although a small regional problem may not appear immediately. If certificate requests fail for you, try again shortly and check whether the error affects renewals as well as new certificates. Our last recorded outage was {LASTDOWN} ago.
help What is the Let's Encrypt server status?
The Let's Encrypt server status currently reads {STATUS} on our monitor. The page tracks reports from people requesting or renewing certificates, so a quiet result can miss a small local fault. For a wider Let's Encrypt network status check, compare this result with the error shown by your ACME client and test the affected domain from another connection. The current 24 hour uptime figure is {UPTIME}%.
help Why is Let's Encrypt not working today?
Let's Encrypt not working today can come from a service issue, but a failed ACME challenge often points to DNS or web server settings. Rate limits can block a request even while the certificate service is operating normally. If you searched for "Let's Encrypt outage today 2026," compare the report count above with the exact error in your client before changing configuration. Check that the challenge URL is reachable and that your domain points to the expected server.
help How do I check if Let's Encrypt is down?
Use this page as a Let's Encrypt down detector, then read {STATUS} beside the recent report count of {REPORTS}. A sudden rise in reports gives stronger evidence than one failed renewal from a single account. If you are asking "is Let's Encrypt working," test a certificate request again after checking your DNS and challenge response. The service can be up while your server blocks validation traffic.
