Missing TGrid token

O²
1

Dear Experts,
I am to run simulations with o2-sim and keep getting the error message TGrid::Connect returned nullptr. May be due to missing alien token.
I don’t know why this appears since I have my certificates in place and I can run alien-token-init. Here is the output of alien-token-info:

[O2/latest] ~/Walice/PbPb_sim $> alien-token-info
DN >>> C=ch/O=AliEn2/CN=Users/CN=slokos/OU=slokos
ISSUER >>> C=ch/O=AliEn2/CN=AliEn CA
BEGIN >>> 2023-03-23 09:12:49
EXPIRE >>> 2023-04-23 10:12:49

The last few lines or o2sim_workerlog0 contains this error message and another one about a missmatch which might be related, might be not.

I have a fresh O2 installation.

Any advice is welcomed!

Thank you, Sandor

I generated a new certificate but that didn’t help either. Any idea what could be wrong?

ps.: I just did git pull --rebase today and re-build with ninja install today.

I didn’t mentioned that I use Ubuntu 22.04 LTS under WSL2 from Windows 10. Probably the issue was that the WSL2 doesn’t start in administrator mode and has no privilege through the firewall. After I run WSL2 as administrator and re-install O2 from scratch, it works.
