Hi @pur-jus, thanks for raising an issue. I'll research this one in the near future. As a current workaround I may suggest you to run PlantUML with Docker

[MikhailKravets]

Hi @pur-jus, could you please take a look whether bare requests package can make a request to PlantUML?

@MikhailKravets anyway we can disable ssl verification ?

[MikhailKravets]

Yes, it is possible, as stated in requests docs. And the solution is very simple. We need to add a new parameter (for example, verify_ssl: true) to mkdocs.yaml and read it in the plugin.

Hey @MikhailKravets , as per this commit, the ability to set ssl verification as false has been rolled back. Could you help me understand why so?

[MikhailKravets]

Hi @RishabhDev42, I believe it was just a human error. I don't see any particular reason for its removal. Thanks for bringing this up! I'll add it to the project with the next release.
