Steam error 53
Another program is interfering with Steam
Steam Support lists this code under its 'servers unavailable or too busy' messages and says it is usually fixed by dealing with software on your PC that stops Steam from working normally.
Fix it
How to fix error 53
Go through Steam's 'Programs Which May Interfere with Steam' list (antivirus, firewalls, VPNs and similar tools).
Disable or uninstall the programs on that list, then restart Steam and test again.
Scan your PC for spyware, adware or viruses if the error continues.
