Yes it is nginx

Guacamole file below: 

server {
        listen 443 ssl;
        server_name myservername;

        access_log   /var/log/nginx/guacamole.access.log ;
        error_log    /var/log/nginx/guacamole.error.log info ;

        ssl_certificate /etc/letsencrypt/live/myservername/cert.pem;
        ssl_certificate_key /etc/letsencrypt/live/myservername/privkey.pem;
        location ~ /.well-known {
                allow all;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection $http_connection;
        location / {

Is Guacamole behind a reverse proxy like Nginx or Apache?

Problem with : 
File upload 
File Download 

1, Should I access the guacamole server using http  all works well. 
2, Should I access it using https then 
a. I can upload a file with max size 1Mbyte 
any file bigger than 1Mbyte will receive  and error You do not have permission to upload
this file. If you require access, please check your system settings, or check with your system
b. Downloading from the RDP to the client machine always gives an error 
Disconnected : you have been disconnected however it gives the options to go home, reconnect
or logout 
c. Printing does not work 

I can see the following error line into my guacamole error log : 
reported that client prematurely closed connection, so upstream connection is closed too while
sending to client 

By the way the above scenario is for both private and public domain (I tried it with both
and same behavior) 

Could someone  please help ?
