My guess other agents are sitting on different machines, did you verify that the credentials are the same between the different clearml.conf files? Maybe @<1523701087100473344:profile|SuccessfulKoala55> might have an idea

ENV variables are the same but a KRB5CCNAME that appears in a working machine and does not in a non-worker machine, could this be it?

Seems so, I'll put it my IT group into it, thanks for the hint!

It looks more like a network/firewall issue and/or certificate issue than clearml credentials related

What specifically? they are sitting in the same VPN network as far as I know and as said before I can ping from one server to another

Sure I do since I can connect to it with my other agents

Hi @<1523717803952050176:profile|SmoothArcticwolf58> , can you describe a bit about the network between the agent and the new server?

And you're sure that clearml.conf points to the correct server with the right credentials?

@<1523701087100473344:profile|SuccessfulKoala55> I'll try and update

@<1523717803952050176:profile|SmoothArcticwolf58> can you compare env vars between successful agents and the one that doesn't work?

If you want me to run some tests or some code to give you additional info, I sure can @<1523701070390366208:profile|CostlyOstrich36>
