OpenVidu v3 supports domain-free deployments using `sslip.io`. However, if you recently deployed without a domain and are experiencing a [LetsEncrypt rate-limit](https://letsencrypt.org/docs/rate-limits/#new-certificates-per-registered-domain), this is likely due to an ongoing rate-limiting problem with [sslip.io](http://sslip.io) (see [cunnie/sslip.io#108](https://github.com/cunnie/sslip.io/issues/108)).

Until this is resolved, we recommend using your own domain name instead.

When `sslip.io` (or any domain) fails to acquire a valid SSL certificate, your browser will display an `ERR_SSL_PROTOCOL_ERROR` when attempting to access the deployment URL.

To confirm this is the issue, check the Caddy logs on your Single Node or any Master Node. SSH into the node and run:

```auto
sudo su
docker logs caddy

```

You should see an error similar to this:

```auto
{"level":"error","ts":1770908645.276268,"logger":"tls.obtain","msg":"could not get certificate from issuer","identifier":"openvidu-cjuzkgrx-13-58-233-208.sslip.io","issuer":"acme-v02.api.letsencrypt.org-directory","error":"HTTP 429 urn:ietf:params:acme:error:rateLimited - too many certificates (50000) already issued for \"sslip.io\" in the last 168h0m0s, retry after 2026-02-12 15:04:09 UTC: see https://letsencrypt.org/docs/rate-limits/#new-certificates-per-registered-domain"}
{"level":"error","ts":1770908645.276335,"logger":"tls.obtain","msg":"will retry","error":"[openvidu-cjuzkgrx-13-58-233-208.sslip.io] Obtain: [openvidu-cjuzkgrx-13-58-233-208.sslip.io] creating new order: attempt 1: https://acme-v02.api.letsencrypt.org/acme/new-order: HTTP 429 urn:ietf:params:acme:error:rateLimited - too many certificates (50000) already issued for \"sslip.io\" in the last 168h0m0s, retry after 2026-02-12 15:04:09 UTC: see https://letsencrypt.org/docs/rate-limits/#new-certificates-per-registered-domain (ca=https://acme-v02.api.letsencrypt.org/directory)","attempt":3,"retrying_in":120,"elapsed":187.594160281,"max_duration":2592000}

```

To resolve this, you can either wait for Caddy’s automatic retry to succeed, or restart your node.  
The retry interval is a custom exponential backoff, you can check it [here](https://github.com/caddyserver/certmagic/blob/707ebd945588a33c5db0b48dd243d81019773b6a/async.go#L166-L190)

If the issue persists, configure your deployment with a custom domain instead by modyfing the parameter `DOMAIN_NAME` of…

Single Node:

```plaintext
/opt/openvidu/config/openvidu.env

```

Elastic/HA:

```plaintext
/opt/openvidu/config/cluster/openvidu.env

```

… configure your DNS to point to your IP/Load Balancer and restart with …

```auto
systemctl restart openvidu

```
