I had a look at the related issues, I am not sure how others are still having a problem after it was reported as solved. I did install the ca certs into the using java keytool, however I have no idea which ca store is used by pycharm. could you please help us with the correct ca store pycharm uses?

Please note: I tried disabling https on my remote jupyter notebook server and pycharm works fine over http, but i dont want to leave remote notebook unsecured

Thank you,

Let me get more info and I'll get back to you later on this.

Meanwhile, are you able to access your remote notebook from browser over HTTPS? Is connection fully protected when you do that? (no waring about self-signed certificate and such)?

Yes I am able to access the remote notebook from browser using https and the connection is protected. I am using certs from letsencrypt and not using self signed certs. There are no warnings as well about the connection.

Thank You

Here's a comment from user who also use "letsencrypt" certificates and had similar issue: https://youtrack.jetbrains.com/issue/PY-35376#focus=Comments-27-3673343.0-0

Could you please try his recommendation?

Yes, In fact, i have started my work around with their recommendation. for some reason it doesnt seem to work.

Hey, sorry for the late reply.

PyCharm is using the default keystore which is located in `<IDE_HOME>/jbr/lib/security/cacerts`

You can import certificates there using keytool, or you can make a copy of this keystore and specify it in VM options.

You may find this article useful: https://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed/

Prior to adding to the PyCharm keystore, it wouldn't even connect.

After adding the self-signed cert to keystore based on above instructions, the configured server is accepted and connected.

However, when executing notebook cells, requests to the notebook server are still made over http vs https resulting in the following error on the notebook server:

W 02:49:16.578 NotebookApp] SSL Error on 12 ('<ip address>', 64072): [SSL: HTTP_REQUEST] http request (_ssl.c:852)

I too followed solution provided by Andrey Resler to add the SSL certificate of remote jupyter hub server.

I can connect to jupyterhub server and can see the published file.

but in Pycharm I get "Run Error" and no result preview.

when checked "idea.log" below is the error message "Unhandled Jupyter error "
