No Agents Connected


I’m trying to setup private instance using the following instructions but somehow I get no test agents are connected.

Server is a linux machine and I have set up agent in windows.
Here is the installation check-

Test Locations

No test agents are configured to render video

Local : WPT Agent Machine
TestAgent : TestAgent Location - No Agents Connected

I see the following in server log when I run the agent
/work/getwork.php?shards=1&reboot=1&location=TestAgent&software=wpt&version= HTTP/1.1" 500 358 “-” “WebPagetest Driver”

I could see TestAgent using /?hidden=1 but it doesn’t appear in drop down when accessing the url. Any pointers will be helpful.

This looks like the agent is getting a HTTP 500 response from the server - what happens if you try the same GET request manually in a browser?

Also what does the httpd error log have in it?

Thank you Andy for your quick response. I fixed 500 internal server issue and now getting HTTP 200 from agent.

However, the problem remain same. As I still do not see any agent connected. Not sure, what I’m missing.

PS- 500 error was due to log errors flag was not set in php.ini.

I don’t see any error in the logs. Any pointers, anyone?

i’m also running into the “no agents connected” error and don’t see any wpt server logs at all. http logs don’t give any useful info either

I didn’t hear any update on this request and to move forward, unfortunately, I had to rebuild the server & agent on the same machine to get it to work.

this error message is really annoying. i also now see the 200 code in the apache logs. i’ve looked over my locations.ini file multiple times and cannot spot any issues with it. what’s really perplexing is that i have 2 other agents set up and working the exact same way. the wpt server logs give me nothing

I couldn’t find your recent response to reply so replying it here…

Thank you for keeping me a posted. Can you please point me to the doc where you found the solution to this. It will be nice to document this solution in the thread for others.

I will keep the solution in mind while building other server/agents.:slight_smile: Thank you once again!! Great stuff.
