Mobile hotspot temporary network error

I have a Samsung S22 Ultra and I have a very similar issue with the exact same error message. Sometimes, I can fix this by restarting my phone, but other times, it doesn't matter how many time I restart it - it won't turn on. It's a very frustrating problem. The other day, when I needed it the most, it wouldn't work. It's been at least 3 or 4 months that I've had this issue - I'd say it works about half the time and I use it maybe 2 or 3 times a week.  This seems like it might be firmware related.

We have tried all this and it doesn't last. Meaning after the restart sure my mobile hot spot works. But after I turned it off and try again later - nope not working and I have to restart yet again. This happened I would say after the latest Software update - week of 2/13..... I believe it's a firmware issue now. Never ever had mobile hot spot not work until now and I have been a customer with ATT for a long time.

@ATTHelp Thank you for the response. I've seen these steps before in other posts about the same issue, so I have tried them all many times. I've even done the network reset, which wipes all of my bluetooth and wifi settings, but the issue still persists. I did have the AT&T Active Armor (I think that's the name) on my phone and I've heard that there were some issues with that which prevented Mobile Hotspot from working properly. I've uninstalled it, so I'll see if that does anything.

@henryarroyo  You rock! this works - thank you! * so grateful that removing this Active Armor worked! Kristin

100% its the 'new' Active Armor. More specifically, its the VPN enabled by Safe Browsing. I know, because I spent hours trying to resolve the issue with Tech Support, only to be told I "HAD" to reset my Network settings. That isnt cool, and requires customer that isn't knowledgeable to go and delete all stored wifi and Bluetooth saved...a huge undertaking if you have multiple networks and devices saved. It's sad @ATTHelp doesn't recognize the root cause and resolution in this thread, so their techs aren't wasting people time by phone. However, @HenryArroyo, no need to Uninstall Active Armor, you just need to disable "Safe Browsing". When I need hotspot for my son's tablet, I just disable safe browsing (turns off VPN), turn on the hotspot, then enable again when he's done. I only get the 'Temporary Network Error' when safe browsing is enabled. AT&T, do better! Active Armor VPN has a bug killing hotspot...fix it!
