Domain Name Not Accepted in Wijmo (Validation Error)

Background:

When adding a hostname/domain to a Wijmo license (e.g., while generating a Distribution Key), the portal validates the text you enter. If the entry doesn’t match accepted hostname rules, you may see an error like:

“The hostname 111.hostname.tld is not in a valid format.”

This article explains common reasons the portal rejects a domain and how to fix them.

Steps to Complete:

1. Check for formatting issues
2. Avoid patterns the validator blocks
3. Try a DNS alias if the label is numeric-only
4. Re-submit the cleaned hostname
5. Still blocked? Contact support

Getting Started:

Check for formatting issues

• Try to enter only the hostname (no http://, https://, paths, ports, or query strings).
• Remove leading/trailing spaces, quotes, or hidden characters.
• Ensure labels are 1-63 characters use only a-z, 0-9, -, and don't start/end with -.
• Avoid underscores (_) and double dots (..)

Avoid patterns the validator blocks

• It's possible our validator may reject numeric-only labels (e.g., 111 in 111.domain.tld) to prevent confusion with IP addresses.

Try a DNS alias if the label is numeric-only

• Create a CNAME such as w111.domain.tld → 111.domain.tld, then add w111.domain.tld in the portal.

• Alternatively, rename the subdomain (e.g., app-111.domain.tld).

Re-submit the cleaned hostname

• After correcting the value, add it again in the portal.

Still blocked? Contact support

• Reach out to Mescius support. We can manually add domains (including special cases like numeric-only labels or required wildcards).
