External interpreter not working. Error: "Can't run remote python interpreter: Can't get remote credentials for deployment server"

Hi,

Please take a look at the issue https://youtrack.jetbrains.com/issue/PY-33983

Does the issue reproduce after you restart PyCharm? Please try to delete and re-create the remote deployment and project interpreter.

Deployment settings: File | Settings | Build, Execution, Deployment | Deployment

Interpreter settings: File | Settings | Project: basic | Project Interpreter

Make sure that the current deployment is marked as "Default". Additionally, please delete `.pycharm_helpers` directory on the remote host, in user's home.

If after this the issue is still reproduced, please add the following lines to "Help > Debug log settings":

#com.intellij.ssh
#com.jetbrains.plugins.webDeployment

Then, reproduce the issue, and provide logs according to https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files

Thanks, with a similar issue, after the connection suddenly started to give the given error, restarting did not help yet, but deleting the remote deployment & interpreter, and adding anew helped me (I did not need to remove the .pycharm_helpers on the remote in my case)

For me it helped to do the following:

1. Delete ALL(!) the remote deployment and project interpreters for a particular remote machine.

2. Restart Pycharm.

3. Recreate thet remote deployment and project interpreter for the remote machine.

4. Restart Pycharm.
