The server freezes for 1-2 minutes

Hi guys. When the server is frozen, in the console this:

Code:

ERROR building certificate chain: System.ArgumentException: certificate --->
System.Security.Cryptography.CryptographicException: Unsupported hash algorithm: 1.2.840.113549.1.1.11
at Mono.Security.X509.X509Certificate.VerifySignature (System.Security.Cryptography.RSA rsa) [0x00000] in <filename unknown>: 0

 

How can I ignore? The server freezes for 1-2 minutes. It can somehow fix it?

 

No. During the work!

 

No. This occurs randomly. Sometimes once an hour, and sometimes less frequently.

 

my server has freezed in the past, here are some of my causes

• QuickEdit is enabled on command prompt
• during the server.save period
• On plugins that scan. I.E BetterStability and Anticheat

If i were you, i would go Vanilla, test it out, if you're still freezing then check server hardware/network
