PR_CONNECT_RESET_ERROR on certain websites (this error is not present in Troubleshoot Mode or other browsers)

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

  • DNS over HTTPS turned off
  • Uninstall all add-ons
  • Reinstall Firefox
  • Create new profile and set it as default
  • Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

Update: the websites seem to work if I try to keep refreshing it until the error does not show up. This is not supposed to happen since I can immediately access the website on my phone connected to the same network.

I also tried switching between using wireless connection and ethernet (on the same network) and it doesn't have any effect.
