Firefox not loading a website

Hi,
When I'm trying to open github.com in Firefox, it stucks on "Waiting for github.com...".
In other devices on the same network everything's loading.
The website is also loading correctly with lynx, so it has to be the problem with Firefox.

Any help is appreciated.

Re: Firefox not loading a website

Hello. Firefox uses⁽¹⁾ different DNS servers than the rest of the systems. That may be a hint that you’re receiving a different address and this causes the connectivity issues. What are your global (system) DNS settings?

If you wish to compare, what Firefox resoles an address to and what glibc does:

• In Firefox’s Developer Tools, in Network tab, you may add “Remote IP” column.

• For system:

  getent ahosts github.com

You may try to determine from that if you have connectivity to these addresses and, if not, where the problem may lie (e.g. with mtr).

____
⁽¹⁾ By default. This is controlled by settings: Privacy and security → DNS over HTTPS. But do not turn DoH off only to circumvent this issue, except for debugging.
