Hello MIP. I'm reaching out this way as this seems to be a re-occurring issue. My BBP client was happy until this last mandatory upgrade. After upgrading, it will not connect to any peers. I have gone as far as completely removing BBP off of my system and deleting the residual files/folders and then re-installing as if I were a new user. Even without my wallet.dat and config file, it will not connect to any peers. I have attempted disabling Windows Defender firewall (Win10) and have also added the two IP addresses in my config file for the nodes you mentioned the last time I had connection issues. Any ideas what to try next? Thank you for you time and consideration on this matter.
I believe your IP was banned temporarily (for being on an old version). Hopefully, you saved your peers.dat and that will go through all your peers and it'll eventually find one that didn't ban you. Alternative is to get yourself a new IP temporarily: tether to your smartphone, use OpenVPN and find a free open server online, etc.
I have the same issue. I will try your suggestions and report.
