Cannot update JOpensim due to errors with JopenSim Package and JOpenSimRegister

Hello I am not sure this is the proper area to post this.
I am trying to update JOpenSim within my Outworldz/DreamGrid server. When I get to the admin page and click update these are the two items that show up and error out when trying to update. prnt.sc/y6q9aFZ_0sme

I have not been able to update this in some time and I am just coming back to this issue now that I have time. Any help would be appreciated.
Thanks

Hi VinnyB

The update server should work though ... can you open the urls manually? (e.g. update.jopensim.com/pkg_jopensim.xml )

Mind that jOpenSim is still not compatible with PHP8.x (I know I'm really late).

In case you can open the url but your server still not, pls let me know your grid's hostname or IP address, so I can check if there is currently any firewall issue for it.

Don't post it here public, rather send me a private message or email.
