Balance 30 quit with latest firmware

I have 3 wans. Everything was fine until the latest firm ware. Suddenly no internet access. I rolled back to the prior version. Still no access. All 3 wans show connected and have appropriate ip addresses and dns configurations. I’m about out of hair! Was there a setting change that stuck that I just can’t find? Please help!

save your config, then do a factory reset, see if you still have the same issue.
