Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 22.2.0.2
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04.3 LTS

PHP version (eg, 7.4): 7.4.3
The issue you are facing:
We no longer have an IIS proxy, and so I am moving Nextcloud beyond it. We are now unable to open the site on an external ISP. It opens fine internally.
Is this the first time you’ve seen this error? (Y/N):
Yes
Steps to replicate it:
- Shut down IIS proxy
- Remove all overwrite* directives, trusted_proxies, and forwarded_for_headers directives in config file
- Restart Apache
- Ensure network firewall routes traffic to Nextcloud instead of IIS proxy
- Attempt to log view site from an external ISP
