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
[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
