The community member is experiencing issues when trying to add a custom domain to their service. They are getting an error when trying to configure the domain automatically, and are also encountering issues when trying to manually add a CNAME or TXT record. The IONOS service does not allow the use of '@' for the CNAME or '__webstudio_is' for the TXT record. Another community member has mentioned a similar issue with GoDaddy.
When trying to add custom domain and click configure automatically I'm getting the following error (see attached img). Please note: I already added this domain earlier using the same approach but now it does not work. When trying to do it manually I'm getting error when trying to add cname and/or txt. IONOS doens't let me to use '@' (cname) neither '__webstudio_is' (txt) as name. Do someone experiencing the same issue?
