Sounds like you are running a custom proxy in front of the site that is timing it out.

yes
we use a custom nginx proxy outside.

4

Looks like you need to amend config on the custom nginx proxy outside then

sometimes we can access the web normal
when the request time is not execeed 5 seconeds.

6

so all the config can work right.
but when the request exceed 5 seconds we just get Oops
I doubt there is some restiction about the reqeust exceed 5 seconds.

the custom nginx config outside as below

server {
  listen       9000;
  server_name  localhost;
  root /opt/nginx/portal;
  location ~* ^.+\.(jpg|jpeg|gif|png|bmp)$ {
    access_log off;
    expires 30d;
    break;
  }
  location / {
    index index.html index.htm;
  }
  
  location ^~/forum {
   add_header 'Access-Control-Allow-Origin' '*';
   add_header 'Access-Control-Allow-Credentials' 'true';
   add_header 'Access-Control-Allow-Headers' '*';
   proxy_pass http://unix:/opt/oca-forum/shared/ocaforum/nginx.http.sock:;

Try removing the reverse proxy and letting the container bind to the 80/443 ports directly and see if the problem persists.

12

thank you!
but I must use the outside nginx for there are not any more port for mydiscourse.

13

I have enter the discourse container and run

curl http://localhost:3000/forum then I get the same error

I use your open discourse
I just need to use a outside nginx and need a subfolder for the url path
@Falco

15

maybe there are some reason about the db
I find the db is very slowly.
I have changed the db_timeout = 10 ,then we get error after 10 seconds.
maybe I should let the db fast.

16

I have fixed the problem. the 5 seconds setting is a default db setting. we has change the setting as below:

DISCOURSE_DB_TIMEOUT: 10000
DISCOURSE_DB_CONNECT_TIMEOUT: 10

and more
we find the db is very slowly.
and we have use a new db on linux instead of the old one on windows.

thank you all the same. discourse is very wonderful.
