Hello,
I have a problem using the RPC. It was working properly before I started to use try/except in the wrong way. It seems it tries to connect to an old non-existing one. I have this problem when I run it in Sublime (Mac side), Grasshopper on Rhino Windows but no problem on Grasshopper on Rhino Mac oddly.
Is there a brute manner to force it to reinitialise?
Thanks,
Robin

Would using `Proxy().stop_server()` help? Alternatively on mac, going to the Activity Monitor and killing the active process could do. On my computer this shows up as `python3.x`.

Still not working. The error occurs at the instantiation. And restarting my computer does not solve it and killing python via the Activity Monitor neither.

hi robin,
i need a bit more info to help solve the issue.
also, what do you mean by “before i started to use try/except in the wrong way”?
and as a side note, on windows the process running the server will show up on the “Details” tab of the “Task Manager” under “pythonw.exe”…
a method for starting RPC that should always work is to use the Terminal/Anaconda Prompt.
```bash
conda activate robin
compas_rpc start
```
or, more explicitly
```bash
conda activate robin
python
>>> from compas.rpc import Proxy
>>> proxy = Proxy()
>>>
```
let me know how that goes…

Hi Tom,
I tried both methods but the RPC doesn’t appear to start. I aborted the first method because nothing happened after a minute.

I tried to reinstall compas with
> pip install -e .
but the same occurred.

can you try with a clean environment? something like
```bash
conda create -n testrpc python=3.7 --yes
conda activate testrpc
cd path/to/compas
pip install -e .
python
>>> from compas.rpc import Proxy
>>> p = Proxy()
>>> p.stop_server()
>>> p.start_server()
```

The same happened in the new environment at
```
p = Proxy()
```
with this error

I also tried in a new environment from a new folder for COMPAS, but it was the same.

is there anything worth mentioning that happened with your computer before it stopped working? OS update, new installed software, Anaconda installation, …?
