Hello everyone!
This is the second time I’ve encountered a strange problem. At some point, for no reason, some sites become unavailable. This happened with github before. The strange thing is that the site was unavailable in Chromium, but opened normally in Firefox. I didn’t change any firewall settings. This happens suddenly. What’s even stranger is that during the same session, after some time (2-3 hours), the site became available in Chromium as if there was no problem.
Now it happened again, registry npmjs suddenly became unavailable. It doesn’t open in Chromium, npm can’t download packages, but everything opens in Firefox. Again, there were absolutely no actions that led to this, everything happens suddenly.
Has anyone encountered this? Is it possible that the computer is hacked?
The fact that this was temporary points to errors outside your control, with your network connection or internet provider - were you able to check access to the same websites on a phone at the time?
As to the subject of your computer being hacked - this sounds more like groundless paranoia than anything else (something we perhaps expect to experience when using Windows - but groundless paranoia has no place with Linux).
You can be fairly sure that there’s no kind of hacking I can imagine which is going to give this kind of symptom.
To troubleshoot this, I would have my phone at the ready - and if my desktop refused to connect, I would fire up Firefox in the phone and try it there…
From there, I’d think to disconnect the computer, and use my phone’s tethered connection to again test the failed browser.
You must work out a way to narrow down this issue - do you have a spare/default Firefox profile to switch to and re-test?
It’s hard to figure out what you have thought to try yourself whilst waiting for an answer.
Thanks for the advice!
I can open this site from any other device connected to my home wifi. The site is unavailable only on the computer in kde neon.
On the computer, I switched to another wifi (distributed mobile Internet from the phone) and there is no problem - the site is available in all browsers. Then I returned to the previous wifi and the site is also available, npm loads packages.
But after some time (about 10 minutes), the site is unavailable again.
I understand if the wifi completely prevented using the Internet and a reconnection was required to fix it, but only one specific site becomes unavailable. I don’t understand why this is so. The problem is only when using kde neon.
I will continue to observe.
It sounds, to me, like an issue I had with a condominium shared WiFi network, where the Office tried to set up rules to ban folks from doing more than just browse - block downloads, or torrents etc. and I would get randomly blocked…
However, not easy to work out why this would be exclusive to both KDE Neon and one specific WiFi network.
