Cannot Browse to vCenter Server

Within the last few days, I have been unable to browse to our vCenter server using Firefox. When I do initially, I get the usual certificate error. Once accepted, I get an error that Firefox cannot connect to the server.

I receive the same error in Private mode as well.

I am able to browse without issue using Chrome which leads me to believe the problem is with Firefox.

Any help would be appreciated.

It appears the issue is with the DNS in Firefox. Even with DNS over HTTPS disabled, the browser still has https://mozilla.cloudflare-dns.com/dns-query as the DoH URL.

The only way to fix the issue was to add an entry in my hostfile for the server.

Please fix your browser.
