Parallels Access does not use internal cert store

I've tried to configure Parallels Access both at home and the login is not working probably because the TLS decryption implemented at both places. It seems Parallels does not use Mac's Keychain where trusted root certificates are stored. It should... or at least the servers used for this login should be documented, so we can put it on exception list

If anyone figured out what servers should I put on exception, please reply

Thanks
