@GentleRV Thx, for reporting the issue.

For me it is not clear whether this is a bug or a configuration issue.
When you provide server logs, we could take a closer look at this.

Could you also elaborate on the actual behavior:

• How does the connection fail?
  • If you see an error about the connection failing, what is the error message?
• If you see an error in the UI, what is the error message?
