OneAgent Failed to connect to the environment at port 443

oriole237 — Fri, 13 Jan 2023 07:38:19 GMT

Hi,

I had to install oneAgent once on a host machine for my first monitoring environment without any problem.

I had to create another environment with different email account and download oneAgent linked to it to install in the same machine after uninstalling the first version installed but I have this problem: failed to connect to port 443

but the installation was successful

Please what can I do ?

Hello @oriole237

The easier was is to check the One agent logs in error on /var/log/dynatrace/oneagent or ActiveGate logs and identify the exceptions encountered.

Are you able to do a telnet https://{environmentid}.live.dynatrace.com 443 from your host ?

Do you have a proxy where allowing the domain *.live.dynatrace.com ?

Otherwise you could contact chat support with the exceptions identified on agent logs.

Regards.
