Thanks & cheers,

Hi,
Same problem here.
NC 22.2.5 (Non Docker install)

All 2 behind SSL connection, access from web are ok
When I insert server adress (https://docs.xxx.xx/) in the OnlyOffice Section in NC Parameters, got a green message that said version 7.xxx are ok
RP Nginx
Only Office Connector are up to date (7.3.2)
Tested on Chrome, Firefox and Edge
Same Error on all web nav
Ditto same issue!
Hi @tj0xin, have you tried to clear the cache and cookies of your web browser?
Yes, i did. Still it shows “This content is blocked. Contact the site owner to fix the issue.” on Edge and Google Chrome.
On Opera it shows blank screen.
I have the same problem on Chrome. On my Mac‘s Safari everything is good. On Firefox just blank white page.
Ok solved by myself today. Just time to prepare the explanation and post it here to help you.
So, hi to all,
1st sorry for my english but I’m french speaking.
The problem comes from the xxx.conf file assigned to your documentserver. It does the job of accessing your docserver.youradress.xyz, so that Nextcloud recognizes it in the Nextcloud OnlyOffice settings but does not allow access to OnlyOffice itself. So here is my 3 step solution.
Behind Nginx Reverse Proxy
1st) Your .conf file without Letsencrypt at /etc/nginx/conf.d (for exemple: docs.conf)
upstream stream-docs {
server local.ip.adress.here;
}
server {
server_name docs.yoursite.xyz;
access_log /var/log/nginx/docs.access.log;
error_log /var/log/nginx/docs.error.log;
location / {
proxy_pass http://stream-docs;
proxy_redirect default;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Host $host;
}
}
2nd) After save push it to SSL with letsencrypt on your Nginx RP
sudo certbot --nginx
3rd) Your .conf file should look like this
upstream stream-docs {
server local.ip.adress.here;
}
server {
server_name docs.yoursite.xyz;
access_log /var/log/nginx/docs.access.log;
error_log /var/log/nginx/docs.error.log;
location / {
proxy_pass http://stream-docs;
proxy_redirect default;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Host $host;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/docs.yoursite.xyz/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/docs.yoursite.xyz/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = docs.yoursite.xyz) {
return 301 https://$host$request_uri;
} # managed by Certbot
server_name docs.yoursite.xyz;
listen 80;
return 404; # managed by Certbot
}
4th) add the commented lines to your .conf file without forgetting to uncomment them (remove the #)
upstream stream-docs {
server local.ip.adress.here;
}
# map $http_host $this_host {
# "" $host;
# default $http_host;
# }
# map $http_x_forwarded_proto $the_scheme {
# default $http_x_forwarded_proto;
# "" $scheme;
# }
# map $http_x_forwarded_host $the_host {
# default $http_x_forwarded_host;
# "" $this_host;
# }
# map $http_upgrade $proxy_connection {
# default upgrade;
# "" close;
# }
server {
# listen 0.0.0.0:80;
server_name docs.yoursite.xyz;
# server_tokens off;
access_log /var/log/nginx/docs.access.log;
error_log /var/log/nginx/docs.error.log;
location / {
# proxy_set_header Upgrade $http_upgrade;
# proxy_set_header Connection $proxy_connection;
# proxy_set_header X-Forwarded-Host $the_host;
# proxy_set_header X-Forwarded-Proto $the_scheme;
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://stream-docs;
proxy_redirect default;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Host $host;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/docs.yoursite.xyz/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/docs.yoursite.xyz/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = docs.yoursite.xyz) {
return 301 https://$host$request_uri;
} # managed by Certbot
server_name docs.yoursite.xyz;
listen 80;
return 404; # managed by Certbot
}
5th) Reload Nginx RP
sudo systemctl reload Nginx
Then go to your nextcloud instance as admin. Go to settings → Only Office and add the documentserver adress, no need to use advanced parameters.
For exemple : https:/docs.youradress.xyz/ (don’t forget the / at end)
that’s all Folks
NOTE: The #Manage by Certbot lines must stay commented ofc 
Hi Irvin,
thanks for posting your solution!
I have the same issue and nearly the same setup(nextcloud non-dockerized and apache reverse proxy). I do not understand what you mean by "…does not allow access OnlyOffice itself. So I’m not able to figure out a solution for apache.
Can you/someone explain it more detailed?
I accessed the outside docserver-https-url from within the docker-container and this seems to work fine.
I found the fix for me.
Since my docker-instance is running on plain http and running on port 80(within the docker container) and the reverse-proxy is handling the SSL, I had to specify the following 2 config options for the reverse proxy:
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"
The full apache2 virtual host section is:
<VirtualHost *:443>
ServerName server.domain.tld
SSLCertificateFile /etc/letsencrypt/live/server.domain.tld/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/server.domain.tld/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/server.domain.tld/chain.pem
ErrorLog ${APACHE_LOG_DIR}/onlyoffice_error.log
CustomLog ${APACHE_LOG_DIR}/onlyoffice_access.log combined
ServerAdmin webmaster@localhost
DocumentRoot /var/www/empty
<Location />
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"
ProxyPass http://localhost:10080/
ProxyPassReverse http://localhost:10080
</Location>
</VirtualHost>
I have the same issue, my document server is install in docker. I post here just for this issue come back again and hope could help others.
my case in using hosting web panel (Centos webpanel: nginx → apache → proxy → (custom-port))
This content is blocked. Contact the site owner to fix the issue is because the webserver domain config doesn’t right. then I place the new config for Apache as below and it does the work
–Don’t forget to replace your real user name path and domain in production
<VirtualHost 192.168.123.120:8443>
ServerName onlyoffice.domain.com
ServerAlias www.onlyoffice.domain.com
ServerAdmin webmaster@onlyoffice.domain.com
