Sandry Logan commented at 2022-11-13T14:09:37Z, updated at 2022-11-13T17:53:47Z I am experiencing the same errors as BlueXBeta. For me the problem started around 02:25 (am) GMT on Saturday 12 November. Up to that point everything was running smoothly. I have not made any adjustments to my code in SL or on Dreamhost for weeks, probably months.

animats commented at 2022-11-13T21:10:33Z, updated at 2022-11-13T21:21:37Z Additional info: My logging, to "animats.dreamhosters.com", worked until 2022-11-10 21:55:08 , the last successful event I logged. It has not worked since. I wrote an LSL script to send a request to https://www.howsmyssl.com, which provides info about what the client is doing with TLS. Nothing looks wrong. The SL servers seem to be making TLS 1.3 requests with an appropriate cypher list. My test program mails that info to me. See sslcheck.txt As for servers, the ones which fail to connect seem to not support TLS 1.1, and the ones which succeed do support TLS 1.1. That may or may not be relevant. I have ticket 222551775 open with Dreamhost, and they say they haven't changed TLS version since 2018. Clearly something is going wrong in TLS negotiation, but what?

JIRAUSER337591 commented at 2022-11-14T09:23:52Z We've been using Dreamhost as well for over 5 years for SL and website and are having these same 5xx error issues when trying to connect from our scripts in world. We've gone so far as to migrate our php to a different hosting provider (DigitalOcean) and when we connect to our php pages on that other host it works fine. We dont want to have to migrate since everything was working just fine for years. We have been chatting and putting tickets into Dreamhost now almost non-stop since Friday around 6pm. Dreamhost is probably annoyed with us by this point as we kept stipulating it has to be them. But now that we have found this bug report and thread, it has come to some relief to know others with Dreamhost are experienceing similar issues within the world of Second Life. Is it SL breaking connections to Dreamhost? Someone please help us!

silversun91 commented at 2022-11-14T15:41:14Z I am having the same issues here with SL connecting to Dreamhost PHP web server. Have communicated with Dreamhost many times and they say they can't see any issues on their end. Been using Dreamhost with SL scripts for many years and it went out suddenly sometime Friday evening and is still going on now. Continuous connection errors, 5XX, no matter what I try. Hope this can be resolved soon. |
Maestro Linden commented at 2022-11-14T18:07:44Z, updated at 2022-11-14T18:07:53Z Thanks for the report, @bluexbeta. We are aware of this issue. It indeed appears that Dreamhost is currently blocking LSL HTTP requests from SL to sites that they host. The block seems to be a response to a very popular LSL script sending requests to one Dreamhost-hosted site at an unreasonably high rate. We have alerted the creator of the LSL script about this issue, and they are taking steps to mitigate it. |
Maestro Linden commented at 2022-11-16T23:49:47Z This issue should be fixed, as of about 10min ago. The site involved in the problematic http requests has been moved off the segment of dreamhost that was blocking LSL requests, and SL's outbound LSL proxies have been migrated to new public IP addresses which are not impacted by the block. The example sites that hit 499 errors when requested from LSL scripts all appear to be responding as expected. |
What just happened?
http requests return 499 status and it seems to affect everybody who hosts their database on dreamhost servers.
In this case, I have coded a combat / spell system and until last friday it worked very well with dreamhost. however now it throws the 499 error and many users report the same issue.
What were you doing when it happened?
nothing special, the scripts i'm using are working well, it's the connection between SL and dreamhost that suddenly seems to be blocked, or broken.
What were you expecting to happen instead?
it used to work fine to connect to dreamhost and run some php scripts there.
Other information
the tech at dreamhost doesn't find any issues on their servers.
Support at Linden Lab doesn't find any issues either.
Yet several users with dreamhost hosting report the same issue since this Friday.
