Usenetserver along with a lot of other servers are having certificate issues at the moment does newsbin do a cert check when connecting and can it be disabled
If you're having issues with newsbinpro itself I would suggest posting in the V6 tech support section. you also should consider at least updating to 6.82 version.
as for the cert errors, it's not Newshosting or Usenetserver. If you have errors from certs, follow the instructions posted for sabnzbd here > https://support.newshosting.com/kb/arti ... on-failed/ These instructions will fix for Windows 10.
