Reinstalled 7.920 from ISO and still have problems. If I reboot with IPS enabled, HTTP/S proxy blocks everything and SSL-tunnel is down. Disable/enable of IPS solves the problem.
Okay, that looks like DNS packets are dropped. Can you please disable those IPS rules that have to do with DNS and try again?
We also know of a defect that has to do with the time it takes to do a complete snort reload, so it's generally a good idea to use as few IPS rules as possible (ie. only those rules that you really need). Less rules -> faster reload -> less likely to get bitten.
