After upgrading to PRTG version 18.104.22.1682 (coming from some 9.1.5 version), at times, I am experiencing some error messages. These are: Timeout, executable did not return. (code: PE018) DNS could not be resolved Socket Error # 11004 (socket error # 11004) DNS could not be resolved (socket error # 11004)
The one with PE018 in it is related to the http full page sensor. The DNS messages show up on the ping sensor, the TCP connect sensor and the http sensor.
Previous versions did not show these errors.
What could be wrong here?
