After Fall'2020 release, some of the third party API calls might fail with SSL related error and it's due to failure of loading certificates truststore by Process Server.
This might happen only if your agent is on Windows and the below agent configuration has backward (\) slash.
Service Type : Process Server
Type : server
Name : trust-store or key-store
Value : contains \ (backslash in the path, ex: C:\test)
Change backward slash '\' to forward slash '/'
If existing value is C:\test, please change it to C:/ and re-start the Process Server
