SSL Error for Attachments on Apple Watch

For a long time now I’ve had issues with my Apple Watch displaying camera or image attachments. My iPhone works just fine and shows the attachments but for some reason my Watch shows this error:

Failed to load attachment URLSessionTask failed with error: An SSL error has occurred and a secure connection to the server cannot be made.

I use Nabu Casa for remote access and have no issues with any other remote connection or anything like that. Any ideas?

Anyone that can offer anyone help? Thanks in advance!
