Looking for a Senior System Admin Apace2, Proxy Pass, Socket.io, SSL configuration

Start with 'admin' I already have an apache2 installed server. I created a basic [login to view URL] testing app on a domain [login to view URL] It's running on pm2. I also have [login to view URL] on my sites-available. Letsencrypt ssl is installed. My problem is when i send a test socket request to [login to view URL], I am having 502 or 403 errors depending on my conf settings. I need to be able to send a request socket server successfully. I am looking for someone who can work an hourly fair price. I don't want fixed price because i will have a lot of server related task requests each week. So that will be a continuos relationship.
