We have only one proxy deployed (6 nodes, 3 allocators).  
UI became unresponsive. We can authenticate, but get no deployments listed.  
Via curl / API we can list all deployments etc.

Searching for reason we've found the following message:

`ALERT] 051/133231 (106) : Cannot open configuration file/directory /app/managedd /haproxy.cfg : No such file or directory [WARNING] 051/133232 (113) : [haproxy.main()] Cannot raise FD limit to 200034, ll imit is 65536. [WARNING] 051/133232 (113) : Failed to connect to the old process socket '/app/dd ata/haproxy/haproxy.sock' [ALERT] 051/133232 (113) : Failed to get the sockets from the old process! [WARNING] 051/133232 (113) : [haproxy.main()] FD limit (65536) too low for maxcoo nn=100000/maxsock=200034. Please raise 'ulimit-n' to 200034 or more to avoid anyy trouble. [WARNING] 051/133232 (113) : Reexecuting Master process [WARNING] 051/141136 (113) : [haproxy.main()] Cannot raise FD limit to 200034, ll imit is 65536.`

The proxy container runs in unprivileged state, so we can't set ulimit to another value.  
How can we proceed?

TIA,  
Agnes

...  
on the other hand the API-Call says proxy is healthy

```auto
 ... api/v1/platform/infrastructure/proxies

"proxies": [{
    "public_hostname": "...",
    "runner_id": "...",
    "healthy": true,
    "proxy_id": "...",
    "host_ip": "...",
    "metadata": {
    }
  }]

```

Solved: Reason certificate has to be renewed.
