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

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

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?

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

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

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

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

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

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?

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