Hi All,
I'm setting up a vault server on a remote PC that I access via Fortinet VPN. I have the vault installed, data backup restored and migrated, I can log into the ADMS just fine. When I try to log in via the Vault client (Server: localhost), it fails.
Looking through the vault logs, I see the following error in the Server Logs:
Error: Soap Exception ( mesg-id = 638938684170382767 ) Exception: TransactionInvalidPrincipal [106]
which seems to indicate a VPN config error (link ) - has anyone had experience with this?
There are also some 306 and 307 errors, but these seem to be from yesterday.
And one other error from this morngng in the Console Logs:

--- End of inner exception stack trace ---I'm not sure, but it could be related to an incorrect login attempt, or something that happened while trying to troubleshoot.
I followed the steps here as well, but nothing has helped so far.
I've logged a ticket with the local IT team to see if they can troubleshoot the VPN, but I'd love to know if someone else has overcome this problem.
Thanks
