Hello,

Any issues on your side ESET?

I have problems activating clients. Here's a snip from my proxy error log:

 

[Mon Mar 30 17:49:43.635202 2020] [proxy_connect:error] [pid 4192:tid 12800] (OS 11001)No such host is known.  : [client 10.1.4.1:50156] AH02327: failed to resolve hostname 'edf.eset.com'
[Mon Mar 30 17:49:43.635202 2020] [proxy:error] [pid 4192:tid 12800] [client 10.1.4.1:50156] AH00898: DNS lookup failure for: edf.eset.com returned by edf.eset.com:443
[Mon Mar 30 17:50:11.620554 2020] [proxy_connect:error] [pid 4192:tid 12800] (OS 11001)No such host is known.  : [client 10.1.4.1:50158] AH02327: failed to resolve hostname 'edf.eset.com'

 

Any ETA on fixing this?

Cheers,

Mihai.

The dns resolvers from RO (tried 2 ISPs) are returning edf.wip.eset.com as CNAME for some reason, while the CF one is returning the correct entries.

If you use split horizon or country/region based resolvers, something screwd up in your config.

 

I resolved my issue by putting a static entry for the moment.

Cheers,

Mihai.
