403 Forbidden, CSRF verification failed. Referer checking failed, does not match trusted origins

Already have.

Chrome Problem only, N/A, no answer provided, and my issue exists in all browsers

No custom port in my setup, N/A

Looked liked a potential solution, but “replace proxy_set_header Host $host:$server_port; with proxy_set_header Host $host; in nginx config”. did not provide a working solution, after inputting credentials end up at a white loading screen" with spinning orb. So it did make the error go away but not a usable fix. Maybe it’s a part of the solution, TBD

Have to change back to proxy_set_header Host $host:$server_port; to stop.

If I missed anything please let me know. Otherwise help, would be greatly appreciated!

Thanks,
Mark
