Error 0x2efd

CCleaner for Windows CCleaner Windows Bug Reporting
1

New installation of CCleaner Professional 5.55.7108 (64 bit) on Win 10.

Two errors:

1) 0x2efd: A connection to the server can not be established

2) An error occured with code: Failed To Make Connection (26)

Both of those are likely from the new "software updater". I know the devs are tweaking it a bit for the next release. I believe it was discussed that the error 26 is akin to server not available at the moment.

Tomorrow will be one week from the bug report and more than two weeks after the release of the paid version 5.55.7108 Pro, which does not work correctly. No corrections? No beta version? All the devs on vacation?

The error 0x2efd continues to display whenever I try to search for updates. I do not believe the application is working as it should. What is the resolution?

5

I just got the same. v5.85.9170 Almost 2 years later.. Validation Server down again!?

Just to clarify, v5.85 is the latest version currently available, so you're not missing out on anything there.

With that in mind, this most commonly indicates that the program is being prevented from connecting out to the internet, typically by security or firewall software. Making an exception for CCleaner will, then, prevent this from occurring by allowing it to communicate out. (And yes, this can even occur if it was working before - like any other software, indeed even more, companies making security software tweak its behavior quite regularly in order to try to prevent new threats.)

Restarting into Safe Mode with Networking can certainly verify this, as in that Safe Mode, nothing should be blocking access on the computer (though your network hardware certainly could still). You can find out how to do so here: https://support.piriform.com/hc/en-us/articles/360045028292

If even that does not take care of the issue, please feel free to use the Contact Us link at the bottom of that form to get in touch with our support team to look into the matter further.

And, of course, you can always download CCleaner manually here: https://www.ccleaner.com/ccleaner/download/standard
