Basic authentication to our SharePoint 2019 farm is not working when proxy is enabled, off it works fine. We just receive a looping logon dialog when good credentials are entered, no errors reported.
- We have the CF origin SSL cert installed on the server.
- We have the Full option for SSL selected.
- Firewall allows https.
Troubleshooting included switching to Development Mode Overview page to disable cache. Same results.
Tanks anyone who might be able to assist.
