Since about Blender 4.2 the Update and Install buttons in the Preference> Get Extensions tab don’t work. I click on one and I get, “install: URL error (<urlopen error [WinError 10054] An existing connection was forcibly closed by the remote host>) reading ‘https://extensions.blender.org/download/sha256:742d5a231763556a7705fda56c1af84c7156fc0b0ef3e490a7609c8765029989/add-on-quick-studio-light-v1.0.9.zip’!”
Blender is allowed through the firewall so I’m not sure what the problem is.
Anyone at all?
Not having any problems at all…running 3.6.9, 4.5.3, 4.5.5 and 5.0.
Check to see if blender connect to internet is turned on in preferences.
Hello
It is turned on in preferences and Blender has access through my firewall.
The blender urlopen error [WinError 10054] indicates that the remote host forcibly closed an existing network connection. This issue commonly occurs when using Blender add-ons that attempt to download external files or connect to online repositories (e.g., BlenderGIS, Get Extensions) and is often caused by network configuration issues such as firewalls, proxies, or unstable connections
Common Causes and Solutions
The error is a general Windows Sockets error, not specific to Blender itself, and usually points to external network factors
Check your firewall and antivirus settings to ensure Blender (and any associated Python processes if using add-ons) is allowed full internet access. Temporarily disabling them for a moment to test the connection can help confirm if this is the issue
If you are using a proxy server (especially in a corporate or school network), it might be interrupting the connection
Also, Changing your system’s DNS servers to public ones like Google’s (8.8.8.8 and 8.8.4.4) can sometimes improve connectivity to specific hosts
Thanks for responding,
I tried all of that and then some and nothing worked. Then out of desperation, I turned on my VPN and it worked. Not the ideal solution but I can live with it.
