Question / Help DNS problems occuring for the first time

[Gòshii]

Hey guys,
I recently wanted to stream again (haven't streamed for like a week or so) and I noticed that when I press Start stream, my bitrate isnt going any higher and this error message pops up shortly afterwards: "Could not connect to server Problem accessing the DNS. (addr: live-fra.justin.tv, error: 11001)"
Now I must say im quite new to streaming but I've never had this error before.
I'm currently streaming to Twitch.tv and haven't changed any settings so far.
So my question is how I can solve this DNS problem. I've tried Google but it just didn't give another clue to whats wrong.
Anyway thanks in advance and have a nice day!

Do you use Comodo Antivirus?

 

[Gòshii]

Hey dodgepong
Yes I do. I currently set it to Game Mode though, so I didnt really think this could be a problem
Regards Gòshii

If you wan't to use Comodo read this:

If you use Comodo and get a DNS error with the latest version of OBS, add an exclusion for the OBS folder and disable auto-sandbox. Disabling Comodo won't help. If you need help to add an exlusion look here: http://imgur.com/a/CvLQl

But uninstalling it and using another antivirus (MSE for Win7 or Windows Defender on Win8) + windows firewall would be better.

Hey varyak
Thanks for the help! It finally works again and I probably know why. I haven't had the latest OBS installed and I had Comodo in Game-Mode. I've changed it back to normal and finally could update OBS. It now seems to work fine. I'll consider this if something like this appears again. Bookmarked. Anyway sorry for wasting your time and have a nice day!
