Hi any body reading this

Several days ago my BOINC 7.6.6 client communicated with BAM. But now it can't. I checked firewall settings, port 80 is free to use, boinc and boincmgr are not blocked. I disconnected my boinc from BAM, success.But connect it again is not possible. Boinc says, that "Notice from BOINC
BOINC can't access Internet - check network connection or proxy configuration.
