The O2 build fails, but locally I have no issue. Is there anything to be done from my side?

Hi @Thorkj , seems the error also happens in other PR in PWG-CF. I tried to check the problem, and it looks like a CI infrastructure issue: the build fails already at the CMake compiler check, before compiling O2Physics code. recc falls back to localhost:8085 because RECC_SERVER is not set, then fails with “Connection refused”.
