I run up the letsproxy instance using the following command.

docker run
-it
-v /var/run/docker.sock:/tmp/docker.sock:ro
-v $(pwd)/proxy/certs:/etc/nginx/certs
-v $(pwd)/proxy/acme:/acmecerts
-v $(pwd)/proxy/conf.d:/etc/nginx/conf.d
-v $(pwd)/proxy/vhost.d:/etc/nginx/vhost.d
-v $(pwd)/proxy/stream.d:/etc/nginx/stream.d
-v $(pwd)/proxy/dhparam:/etc/nginx/dhparam
--name proxy
--net=host
--restart=always
neilpang/letsproxy:latest

But it doesn't work. The logs as following:

WARNING: /etc/nginx/dhparam/dhparam.pem was not found. A pre-generated dhparam.pem will be used for now while a new one is being generated in the background. Once the new dhparam.pem is in place, nginx will be reloaded. forego | starting dockergen.1 on port 5000 forego | starting nginx.1 on port 5100 forego | starting cron.1 on port 5300 Generating DSA parameters, 4096 bit long prime dockergen.1 | 2021/11/01 05:57:31 Generated '/etc/nginx/conf.d/default.conf' from 5 containers dockergen.1 | 2021/11/01 05:57:31 Running '/app/updatessl.sh updatessl' dhparam generation complete, reloading nginx 2021/11/01 05:57:33 [notice] 108#108: signal process started dockergen.1 | 2021/11/01 06:00:20 Watching docker events dockergen.1 | 2021/11/01 06:00:20 Contents of /etc/nginx/conf.d/default.conf did not change.

More info

• My VPS is rented from Tencent Cloud and is set up in China .
• The OS is using Ubuntu 20.04.
• The 443 and 80 ports are used for the letsproxy instance.

Based on this information, could you help to locate the issue? And how to solve it?
