Describe the bug
I'm using Nginx Proxy Manager as a forwarding service for long domain names. However we got one domain that seems to long for the "forward_domain_name" table :D (the forwarded Domain is 279 Chars long)

To Reproduce
Steps to reproduce the behavior:

I noticed it just hang and crash (browser notification: wait or kill) when attempting to input a long name.
