Cannot download from Marketplace after changing properties file BitBucket
After a proxy edit in BitBucket, I don't get it done to download stuff from the marketplace at the BitBucket application.
To start with, I've got two servers. One server thats running Plesk and the other Ubuntu 19.10 with BitBucket. I wanted to access my BitBucket server with an domain. That domain is linked in Plesk and I changed the 'Additional nginx directives' (See the image). Then I've changed the BitBucket.Properties so that my BitBucket sever was secured with SSL, but now I can't download from the marketplace. Before editing the properties file from BitBucket, so you need to access it through the IP, I was able to download from the marketplace.
If I check my console in Chrome I'm getting this Error message but it doesn't make me wiser.. 
Thanks in advance!
Plesk Additional nginx directives: Blue line is the IP of my server. 
BitBucket.Properties: Blue line is domain name
