you know what’s funny about turning it off and on? my home isp had a problem. the uplink packets were dropping very often, downlink was fine. I called tech support.
as usual they said the ‘IT hello’. I said already tried. the guy made me restart everything on call. nothing changed. soon they sent two guys. they came all the way to turn the optical interface off and on and tp change the dns to isp one (obviously I never use that). they soon realized the problem isn’t here and called the isp. after some furious cussword exchanges they told the isp the IT mantra. and voila! they restarted their switch (cutting off internt to an entire locality lol) and everything went normal. that day I knew the true power of that mantra.
this exact same thing happened to me a while ago. I really doubt some human blocked my account though. after hours of customer support call and emails (from another account) it finally got unblocked but neither yhe support agent nor me had any clue what happened.
I learned the lesson and gradually moved the dev accounts to a proton email instead.
