pymapdl TimeOut error when initializing pools

TimeOut error when initializing pools

🤓 Before submitting the issue

[X] I have visited the Troubleshooting section.
[X] I have searched among the existing issues.
[X] I am using a Python virtual environment.
[X] I am using the latest version of PyMAPDL and its dependencies (fully updated virtual environment). You can update them using pip install --upgrade --upgrade-strategy eager ansys-mapdl-core in your activated virtual environment.

🔍 Description of the bug

I have tried on different PCs with different versions of the package (0.69.dev0, 0.68.4, 0.67) to use MapdlPool and it works but some client processes do not connect. I have provided a sharepoint link to the code for a minimally working example.

🕵️ Steps To Reproduce

Run impedance_conductivities.py on this folder ... (ask for link) It relies on input files (exp_plan.csv, dura_thickness_0.33585088029503823.cdb) and 2 helper classes (FieldComputer.py and ExperiencePlanManager.py).

Give it some time, it might work at first but it will fail at some point and console will show output in logger
