fix: Clarify domain expiry warning for TLDs without RDAP endpoints by Copilot · Pull Request #6620 · louislam/uptime-kuma

Copilot · 2026-01-06T19:20:16Z

The warning message for TLDs without RDAP endpoints (.eu, .gr, .pf, etc.) incorrectly suggested filing a bug report and didn't explain why domain expiry monitoring was unavailable.

Changes:

Updated warning message in server/model/domain_expiry.js to explain that RDAP endpoint is missing from IANA database
Added TLD prefix (.eu instead of eu) for clarity
Removed misleading "file a bug report" suggestion

Before:

log.warn("domain", `${tld.publicSuffix} is not supported. File a bug report if you believe it should be.`);

After:

log.warn("domain", `Domain expiry unsupported for '.${tld.publicSuffix}' because its RDAP endpoint is not listed in the IANA database.`);

This affects TLDs that legitimately don't provide RDAP services and cannot be supported through the current implementation.

<agent_instructions>currently, the warning is (for example)

[DOMAIN] WARN: eu is not supported. File a bug report if you believe it should be.

@copilot all logs in this file say log.error("domain", log.warn("domain" or log.debug("domain"

They should be log.error("domain_expiry" and such

Pull request overview

This PR improves the warning message for TLDs that don't have RDAP endpoints listed in the IANA database. The previous message incorrectly suggested users should file a bug report when monitoring was unavailable for certain legitimate TLDs like .eu, .gr, and .pf.

Key Changes:

Rewrote warning message to explain that domain expiry monitoring is unsupported due to missing RDAP endpoint in IANA database
Added dot prefix to TLD (.eu instead of eu) for better clarity
Removed misleading "file a bug report" suggestion that was causing confusion

Copilot · 2026-01-06T19:41:40Z

server/model/domain_expiry.js

        const rdap = await getRdapServer(tld.publicSuffix);
        if (!rdap) {
-            log.warn("domain", `${tld.publicSuffix} is not supported. File a bug report if you believe it should be.`);
+            log.warn("domain", `Domain expiry unsupported for '.${tld.publicSuffix}' because its RDAP endpoint is not listed in the IANA database.`);


There's another similar warning message on line 51 that could benefit from the same clarity improvement. Currently it says "No RDAP server found, TLD ${tld} not supported." but it doesn't include the dot prefix for consistency. Consider updating it to match the new format: "Domain expiry unsupported for '.${tld}' because its RDAP endpoint is not listed in the IANA database."

@copilot all logs in this file say log.error("domain", log.warn("domain" or log.debug("domain"

They should be log.error("domain_expiry" and such

This is a good log improvement, since it allowed me to quickly find the source of endless log warning entries showing:

... [DOMAIN] WARN null is not supported. File a bug report ...

When watching the log while entering a domain name, I notice that every new character entered in the input field generates a new warn log line.

Are there any good reasons for logging at that level, or repeatedly logging unrecognized domain names at every heartbeat?

I can see several reasons for using unrecognized domains.

In corporate environments, the DNS could be configured with split horizon where a private domain is for intranet use, and there could even be unusual names in /etc/hosts.

For my own use, I prefer IP addresses for simplicity (yes really), and that generates those endless log lines.
From my example log:

Are there any good reasons for logging at that level, or repeatedly logging unrecognized domain names at every heartbeat?

No, that is a bug.
In an ideal world, we would only log for one TLD once.

I am not sure why for you there are all of thee entries, did you create a new monitor or have to save for each line

iotux · 2026-01-07T04:36:33Z

I am not sure why for you there are all of thee entries, did you create a new monitor or have to save for each line

To clarify a bit.
The 'null' entries are from several monitors where I have used IP addresses.
For the '.st', it is actually a domain name I own.
For the others, I am not saving the entries. For each and every character entered in the input field, a log line is written

CommanderStorm · 2026-01-07T04:41:48Z

I guess then that part is also a bug

iotux · 2026-01-07T04:45:38Z

I guess then that part is also a bug

Another observation: Monitor pages created previous to this PR does not have the new 'Domain Name Expiry Notification' tick box. I don't know if it is supposed to be automatically updated.

iotux · 2026-01-07T04:56:12Z

I guess then that part is also a bug

A more serious observation. This also happens when adding a Ping monitor.
When entering the plain IP address 10.11.1.123, I get this in the log. This happens with other monitor types as well.
