Firefox can’t connect to the server at scholarship.up.nic.in. What can you do about it?

I routinely am not able to open registration to conferences or other links to long web addresses. This screen message from Firefox appears:

Any time I try to load a webpage on Firefox, I get the error which states "Firefox can’t connect to the server". This occurs when the DNS over HTTPS setting is set to 'off' or 'default'. When the DNS over HTTPS is set to 'custom', the error displayed is "Firefox can’t protect your request for this site’s address through our secure DNS provider. Here’s why: Firefox wasn’t able to connect to firefox.dns.nextdns.io." (it's the same for next DNS or cloudfare).

When I initially opened the DNS over HTTPS settings, this message was displayed: "DNS over HTTPS is not working because we encountered an error (NS_ERROR_CONNECTION_REFUSED) while trying to use the provider Cloudflare". However, this message went away and I have not been able to replicate it.

I have already tried everything suggested in the support article "Firefox can't load websites but other browsers can". I do not have any antivirus software installed. I reconfigured the proxy settings to no proxy. I changed the IPv6 settings. I changed the DNS Prefetching settings. Nothing has worked.

Safari works perferctly fine, Chrome is giving me similar errors.

Sometime in the last week or two, every page starts with a banner that says "you must sign in to the internet to continue". I'm already/always signed in. On those few occasions when I click on the network login link (rather than clicking X to dismiss this dangerous and wrong banner), it shows a very dangerous site and says that site is prohibited. (As it should be.) So why is the banner demanding that I log in (forcing me to click X to dismiss it)? This feels like your site has been compromised, that some malicious actor is forcing this prompt on every page. (And even after I click X to dismiss it, it reappears 10-15 minutes later.

The server not found response started right after two changes: 1) Firefox last update 2) opening an account with Mozilla. It usually works on second request but occasionally not. Thanks for your help in advance.

Why is my location never accurate? It is off by 200–300 kilometers. I am currently in Mae Sot District, Tak Province, but my GPS location shows that I am in Phitsanulok. !?

Firefox is my default browser. Today I attempted to access several different sites and I keep getting a message that Firefox can't find the site. My other browsers have no trouble at all. Something went awry with Firefox. Is it beyond my puny actions to resolve? Do I need to reload Firefox somehow? I can't back anything up because I don't have access to it in the cloud. What am I to do?

Thank you.

Hi, I don't know what is causing this issue but I cannot click on links (on desktop) from my emails it just takes me to a blank page that can't load saying Server not found. I can click on the links using my mobile app. Is this a Firefox issue?

I have tried with Firefox and Waterfox, (I don't use Chrome, Edge etc). I am using gmail.
