on the weekend tried using convex by following the chat app example (https://docs.convex.dev/tutorial/) but got this when setting up:

today I tried a different project with convex using https://better-t-stack.dev and got similar issues:

This is generally due to local network issues, vpn, that sort of thing

twilit galleon Jun 26, 2025, 2:48 AM

#

does Convex block Indonesia? I am not on a VPN and have Warp disabled @elder mauve

#

is there a way I could get more info on how to solve this?

twilit galleon Jun 26, 2025, 8:36 AM

#

went to a different cafe with a different wifi, I am not using VPN and still having this problem

elder mauve Jun 26, 2025, 4:24 PM

#

Can you run npx convex network-test from your project root and share the result

twilit galleon Jun 28, 2025, 4:03 AM

#

❯ npx convex network-test
✔ Deployment URL: https://coordinated-anteater-695.convex.cloud
✔ OK: DNS lookup => 52.54.48.130:ipv4 (1.84ms)
✖ FAIL: TCP connect (AggregateError)

#

any clues? @elder mauve

#

would love to get unblocked to work on it this weekend

elder mauve Jun 28, 2025, 4:06 AM

#

hmm

#

Sparse on details

#

Just learned about this one, each of these tests can be expanded to provide details, rerun, etc, hopefully can shed more light: https://network-test.previews.convex.dev/

#

so your browser is good, it's your cli specifically

twilit galleon Jun 28, 2025, 4:50 AM

#

yeah, any extra debugging ideas? ways to collect more info about the cli connection?

echo sleet Jun 28, 2025, 6:05 PM

#

here are a few, I also put some better error printing the cli network test for the future

ping -c 4 8.8.8.8
ping -c 4 google.com

nslookup google.com
nslookup kindred-parrot-330.convex.cloud

curl -v http://google.com
curl -v https://google.com

@echo sleet fyi i'm open for a quick call if that helps investigate, can't wait to unblock my local setup. I just cooked a very robust app in basically 1 prompt using Chef and I'm blown away by the result. The app is even better than Replit's output with same prompt and so much easier to use, less friction to deploy etc.

hard heron Jun 29, 2025, 10:47 AM

I'm having the same issues on and off since yesterday

#

hard heron Jun 29, 2025, 10:50 AM

twilit galleon this is the output

Getting the same result

echo sleet Jun 29, 2025, 9:25 PM

#

@hard heron @twilit galleon Couldyou both try upgrading convex (just released [email protected]) and running the network test again, the error should be a little better now

Here's another to try, seems like normal network stuff is fine but there are issues with the convex cli:

NODE_DEBUG=net,http,https,tls,dns DEBUG=* npx convex network-test

hard heron Jun 30, 2025, 2:48 PM

#

📎 1jtVT5a.txt

#

Here's the log

#

Convex auto updated when running convex dev, but

#

For a few times after hte update, the first retry would fail, then it would connect

#

Couldnt recreate that afterwards

#

Working fine now

#

The network test passes too

#

#

Nvm it just happened again

#

Here it is

📎 XTPrvWa.txt

#

📎 Anx7742.txt

#

Is this maybe cuz of the vpn? Cuz I have it set to go to Swizerland through sweden

echo sleet Jun 30, 2025, 3:51 PM

#

Possibly, if the number of vpn hops makes it slower than the 250 ms timeout? ~~Try one more:

NODE_OPTIONS="--dns-result-order=ipv4first" npx convex network-test

or

NODE_OPTIONS="--dns-result-order=ipv4first" npx convex dev
```~~

#

no forget those, try:

NODE_OPTIONS=--no-network-family-autoselection npx convex dev

or

NODE_OPTIONS=--no-network-family-autoselection npx convex network-test

echo sleet Jun 30, 2025, 4:21 PM

#

this fix will be in the next client release, from your logs it looks to me like it would fix

echo sleet Jun 30, 2025, 5:02 PM

#

Progress! potential fix in https://github.com/get-convex/convex-backend/commit/1b4888c385fa55a755a9a3936056d3d79257b6dd

try [email protected] and let me know if it's fixed, especially helpful if it's somewhere where you can repro the issue with [email protected]

So, I tried this with the 1.25.2 update, and convex dev works, but this command, and the network test in general fails like this:

- Performing network test...

✔ OK: DNS lookup => 52.200.179.149:ipv4 (170.85ms)

✔ OK: echo 128 B (266.43ms, 480.42149539687847 B/s)
✖ FAIL: Network test timed out after 30s.

#

Gonna try wiht 1.25.1 too

#

Same result?

#

No idea why

Dev is working though

echo sleet Jun 30, 2025, 9:43 PM

#

That failure is totally fine, you just have a slower connection

hard heron Jul 1, 2025, 9:07 AM

#

Guess so

#

I can stream 4k though...

#

Idk anyways, thanks for the fix!

oak edge Jul 2, 2025, 12:35 AM

#

I had the same issue following a tutorial, and the convex package update resolved the issue for me !

#

same for the network-test

1.25.2 fixed it @echo sleet 🙏

#

both dev and network tests are working now

echo sleet Jul 5, 2025, 11:17 PM

#

Great! Thanks all for reporting.

echo sleet Jul 5, 2025, 11:27 PM

#

hard heron I can stream 4k though...

Hm, that's interesting. Stream as in upload? This final test uploads and downloads 4MB and times out after the whole test gets to 30s. The point is to check that the network can break up data into multiple packets and reassemble them. If you can normally upload 4MB and then download 4MB in 20s then this is surprising. But try again with --timeout 60 or more just to see

#

I'll add a message to the network test mentioning this flag.

Yeah, I meant watching/streaming 4k video through the same double vpn, and my upload download speeds are the same, so yeah

Well, the test is passing right now, but it's fine, I havent had an issue since that time, It was just the network test sometimes failing

#

In actual usage, everything was working fine
