I’ve tried twice and this is still happening. At first, I thought it was a machine performance issue, but I resolved that problem.
Hi @laurin1
On that machine could you ping extensions.xwiki.org and nexus.xwiki.org?
Looks like your machine is missing internet connectivity to those.
Thx
Also, can you click on the red messages to see if you can get more details?
A little high to nexus, but I can ping both:

Well, I can click on it, but the text disappears before I can read it (I’m Extension Updater in the Administer Wiki controls, not in the DW) and when the Updater finishes, it clears the screen.
Also, this does not fail for every (extension? not sure what each connection attempt represents):
So, this last time it did complete, but took a very long time and still got lots of timeouts. Once that was done, I upgraded one of the extensions recommended. As you can see got one timeout during that process, but it did finish:
FYI, I’ve never had this issue before.
hmm maybe you could use the Developer tool from your browser to check the HTML DOM and find the full error message? Thx
Tried that. 
Using Chrome, none of that text is show up in the dev tools (not even the “time out” text). I’ll try again.
err that doesn’t seem possible
Ok, the text is there, but dev tools does the same thing that clicking on the link does! If I click on the element with dev tools open, I briefly get the the elements for the connection error, then it closes and “disappears”. Same thing, if I search for the words “timed out”, it shows me the elements briefly, then I’m moved to somewhere else in the dom immediately.
Oh, it’s because it’s constantly being reloaded. I found the DIV that the AJAX process is using to display this content, and because the process is still running, it changes almost constantly.
Ok, I was able to save the page to my desktop while it was running and then extract one of the errors:

https://store.xwiki.com/xwiki/rest/repository/extensions/org.xwiki.contrib.blog%3Aapplication-blog-ui/versions?requireTotalHits=true&start=0&number=-1 seems fast. Maybe you have some proxy blocking it ?
Ugh. We’ve been playing “whack a mole” blocking hackers over the last week and we blocked 5.0.0.0/8. However, our router should only be blocking inbound. I need to figure out why that is not happening. I had not tested store.xwiki.com and that’s at 5.135.69.203.
Thanks for all your help and sorry to waste your time.
