Hey @kiwi8! Cross-posting the solution I shared in the other thread you linked to, to ensure this answer is surfaced for all merchants dealing with the same thing. I did some digging into this and I believe I have discovered the issue. 

Zoho webhosting does not support compacted IP addresses, which in a AAAA record is shown as two colons back to back "::". While there is a whole scope of information regarding compacted vs expanded AAAA ip records, please try your AAAA record like so:

Shopify recommended (most third party domain hosts): 2620:0127:f00f:a::

Zoho webhosting: 2620:0127:f00f:0005:0000:0000:0000:0000

For more details on this - The process of condensing an IPv6 address involves removing consecutive blocks of zeros and replacing them with a double colon `::`. Here's how the given IPv6 address `2620:0127:f00f:0005:0000:0000:0000:0000` is condensed to `2620:0127:f00f:a::`:

1. Remove leading zeros from each block: `2620:127:f00f:5:0:0:0:0`
2. Group consecutive blocks of zeros together: `2620:127:f00f:5::`
3. Replace the consecutive blocks of zeros with `::`: `2620:127:f00f:5::`
4. Add the missing block `a` to get the condensed form: `2620:0127:f00f:a::`

So, the condensed form of the IPv6 address `2620:0127:f00f:0005:0000:0000:0000:0000` is `2620:0127:f00f:a::`. They are the exact same IP address, just Zoho doesn't seem to like the condensed version.
