# Troubleshooting

On this page we'll walk through some of the most common issues that folks run into when setting a custom domain, and explain how to solve them.

<details>

<summary>Why  I have this error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH?</summary>

This error appears because the certificate does not have authorization to be issued.&#x20;

At certain hosting providers you must add **2 additional CAA records** in your DNS:&#x20;

`0 issue "pki.goog"`&#x20;

`0 issuewild "pki.goog"`

*Example from Hostinger.com*

Once done, **deactivate then reactivate** your custom domain in [CUSTOM DOMAIN](https://tip4serv.com/dashboard/domain).

If you still have the error 24 hours later **deactivate then reactivate** again. DNS can take time to propagate.

<summary>Why I have an invalid SSL error when I go to my store?</summary>

Note that you must wait at least 1 hour for your SSL certificate to be created.\
If you still have the error, you have misconfigured your DNS CNAME.

To test your DNS click on the **DNS CHECK** button in [CUSTOM DOMAIN](https://tip4serv.com/dashboard/domain).
