403 Forbidden error when logging in

Hello.

As the title says, I’m getting the following error, when I click logging in, “403 -Forbidden – Access to this resource on the server is denied!”.

First thing I did was to run the Diagnostics tools, which seemed OK for everything except this point, I have screenshotted here: https://prntscr.com/dvx0uq

I have already checked out the Troubleshooter, and it seems like the problem is that there’s no access to the plugin folder. So first thing I did was to contact my host, and ask them to “white-label the url’s” as mentioned in the Troubleshooter. They said that they don’t exclude that or have any control over these things, and told me to ask the plugin community.

I would like to point out that I’m using a SSL certificate, which seems like others also are experiencing trouble with when I go through the forum posts on similar issues. Unfortunately I couldn’t find a solution.
