v1.7.3 v1.7.0.0 Cannot sign in to steam due to Error 503

[Artoo_THM]

Whenever I try to sign up my account in steam, I always get the Error 503 message.

I have not yet been able to come up with a solution after looking through the other forums with the same problem. I have tried using a VPN, and I have no antivirus software other than Windows Defender, and I have also checked my ISRG Root x1 Certificate which is there.

When I checked PRLauncher.log, though, I found this error message which I am not sure is pertaining to exactly.

Warning: Unable to load latest version information

> The underlying connection was closed: An unexpected error occurred on a receive.
>> The client and server cannot communicate, because they do not possess a common algorithm
[/code]

Any help would be appreciated, thank you!
