Some people having ERR_CONNECTION_REFUSED during download or reading a R2 File
Hello, I have a MMORPG server, and I'm using Cloudflare R2 to download the game update.
Majority of players are being able to play the game and update the game without any issues, but starting from today 17th feb 2025, a few players are reporting having issues when trying to open our launcher to do game updates.
It's giving the error; "The underlying connection was closed: An unexpected error ocurred on a send."
After some verification, we noticed that these people was being blocked for some reason from our Cloudflare R2 Servers.
For example, they were getting;
Err_connection_refused
When trying to access the link;
https://download.ultimatedbo.com/patcher_config.xml
For now, the solution is ask they to use Cloudflare Warp (Or any VPN) and it fixes the error, but of course, this is not optimal, the Cloudflare R2 was working fine yesterday without any issue.
Some Cloudflare Support can help-me out about it?

Ps: Some Players which were working one day before, is having this issue as well.
I asked for disable firewall or antiviruses, and nothing. It only get fixed by using Cloudflare Warp or any other VPN services.
Nooone to help??
I'm having the same problem in my app
It's mostly US based, although some users are not being able to see images hosted in R2
If they switch from wifi to data, they are able to see images
I'm not sure why but it seems to be a routing issue, but I haven't found anything online about it which sucks
Yeah, worst thing is that I'm R2 to literally host the Launcher files of my MMORPG, and of course, he needs a full connection to even open the game for new users.
And ask for players to install a VPN to play the game is kind of Shady...
This error is making some users simply give up to even open the game.
@Community Champion @Cloudflare (Server Owner) someone can help us about that?
?pings
Please do not ping community members for non-moderation reasons. Doing so will not solve your issue faster and will make people less likely to want to help you.
By the way, this is witht he Cloudflare VPN
And this the player having the issue, without the VPN.
When reach to the last IP, which is a IPV6, it simply don't connect.
I have experienced the same thing, my solution was adding custom rules with SKIP action for the url containing my subdomain that I use for r2
How can I do that?
Account Home > Select domain (The existing subdomain is connected to r2) > Security (Sidebar in left) > WAF > Custom Rules
And adding rule
1. Create rule
2. Set rule name (Contents are up to you)
3. Field (select URI Full)
4. Operator (select wildcard)
5. Value (https://download.ultimatedbo.com/*) without ( )
6. Choose action (select Skip)
7. Check all parts of WAF COMPONENT TO SKIP
8. Select order (select first)
9. SAVE
Let me know if you do.
I did that now
Did it work?
I'll need to ask to some user that had this issue.
I'll give the result here
Nope, still getting the same issue
