With regards to the first issue of the unsigned plugin.
Please can you confirm how it was installed? Via the web or via the Integrated AppStore.
Please can you also confirm your exact Studio Version in relation to the App Version. 

With regards to the second issue of: The local LanguageTool server is not available. Click Retry to restart the server. Error: Unable to connect to remote server.
The app LangugeTool was developed by a 3rd party developer: By DArek (Post-edit a CAT)

As a result you can try contact them for support?

Alternatively - have you tried to remove the apps and reinstall if need be?
They can be removed directly from the Integreted AppStore under Installed Plugins.
Or directly from Windows Directory: C:\Users\username\AppData\Roaming\Trados\Trados Studio\17\Plugins\Packages

Looking forward to your followup

Dear Lydia Simplicio,

Thank you very much indeed for your feedback. Sincere apologies for my late reply, I was in a field mission in a remote area in Mozambique with very limited access to the Internet.

Regarding the first issue of the unsigned plugin, it was installed via the Integrated AppStore and my Studio Version is Studio Trados 2022 (hope I understood your question and answered it correctly).

With regards to the second issue: "The local LanguageTool server is not available. Click Retry to restart the server. Error: Unable to connect to remote server", I will contact the RWS Support Team for assistance.

Kind regards,

Jorge

You should try to create separate threads for each issue so we can close them off and track them more easily.

On the first one... almost certainly due to an existing version of the plugin in the unpacked folder.  It would be worth resetting and then reinstall the plugins ONLY via the integrated appstore in Studio.  Do not try to manually install anything you already had.

Please delete the following folders and then reinstall your plugins by using the integrated appstore in Trados Studio:

%APPDATA%\Trados\Trados Studio\17\Plugins

%LOCALAPPDATA%\Trados\Trados Studio\17\Plugins

c:\ProgramData\Trados\Trados Studio\17\Plugins

This is another app.  It is not supported by the RWS Support team.
