Update sites can not be reached

Hello,

The Joomla auto update function throws an error when trying to approche the vi-solutions sites:

Update: Could not open update site #66 "vfbase", URL: vi-solutions.de/updates/visforms/extension_vfbase.xml
Update: Could not open update site #67 "vfsubscription", URL: vi-solutions.de/updates/vfsubscription/j3/extension.xml

How can I solve this?

Kind regards,
Jeroen

V1: Which Visforms version is running? 5.3.1
V2: Which Joomla version is running? 5.2.3
V3: Which PHP version is running? 8.1.29

Hello Jeroen,

Thanks for the version information.
Thanks for the precise and complete error report.

The update URLs for both extension.xml files are very available.
Update URLs for both extension.xml files are used by many around the clock.

There are no problems with them except for you.
Even when I click on the links here in the post with the mouse, both extension.xml files open.
It is obviously a problem with your Joomla instance or with your provider.

Question 1:
Are there restrictions for your Joomla instance or via your provider for access to possibly blocked domains or IPs?

Question 2:
Did you try again later and also today?

Possible solution:
Access to both extension.xml files may have returned to normal in the meantime.

Best regards, Ingmar

Hello Ingmar,

As far as I can see no restrictions are in place. Other update sites work without issues.
I just retried but the same error occurs.

Best regards,
Jeroen

Hello Jeron,

There is only one place in Joomla where this error message is thrown.

This error message comes from
- the file: libraries/src/Updater/UpdateAdapter.php
- the function: protected function getUpdateSiteResponse

There is a timeout of 20 seconds.
If nothing comes back after this second, then the message would also be displayed.

Question 1:

If you see the error message in the update manager, can you click on the links in the message and get to the extension.xml files?

As if you were clicking on these links at the top of your post?

Question 2:

Can you attach a screenshot?

Question 3:

Can you start the debugging and attach the report if there is one at all?

How to enable maximum debugging in Joomla Administration before recreating the error:

Dashboard --> Configuration, tab 'System', parameter 'Debug system' = 'Yes'
Dashboard --> Configuration, tab 'Server', parameter 'Report errors' = 'Maximum'

Kind regards, Ingmar

Hello Jeroen,

Thanks for the screenshot.

We have installed your Akeeba backup.
In this Joomla instance of your site, both update links from Visforms in the Joomla Update Manager work without errors.

In addition to the two update links from Visforms, the screenshot also mentions a third update link that is also not available.
This third update link also works without errors in the Joomla instance of your site.

Thanks for the content of the Joomla error file 'error.php'.

Errors in the Joomla Update Manager are, however, more likely to be logged in the following log file:
'\administrator\logs\joomla_update.php'

Conclusion:

Everything is working on your Joomla instance and on the Visforms update links.
In between is your provider and access to the Internet. You should continue to look for the cause there and possibly contact your provider directly with the problem.
I no longer see any connection with Visforms and unfortunately I cannot tell you what exactly might be wrong with your provider and internet access.

Best wishes, Ingmar
