Thank you for the information. I really appreciate finding out the actual problem. I am currently running latest NGINX Proxy Manager. The following configuration appears to be working well for me:
Cache assets: false, Block common exploits: false, Websockets support: true
Force SSL: true, HTTP/2 Support: true, HSTS Enabled: true, HSTS subdomains: true
Custom Nginx Configuration:
`gzip off;`
Thank you, everyone.
