Error: `Domain name is too long`

[summercms]

Hi,

Open https://dnstwist.it/

Add domain name: classicetherwallet.com

Would it be possible to increase the domain length?

I feel the example domain I have given is not too long.

Reading this: https://webmasters.stackexchange.com/questions/16996/maximum-domain-name-length

I would suggest increasing to a max of 63 characters.
