Hello,

Please see AMQP's release notes on this topic -

https://github.com/rabbitmq/rabbitmq-server/blob/main/release-notes/4.1.0.md#initial-amqp-0-9-1-maximum-frame-size

This error is unfortunately not something we can help with.

Best,
Brody

Thanks for the prompt reply.
If i put RabbitMQ in the same project as my n8n, and use the internal railway URL, would it work? I only need to use it within my n8n, I don't need external access.

Yes it would work, but you still need to follow what was outlined in the doc I have linked.

It's still not working. I'm getting a different error now.
Not sure what i need to change, could u please help?

I'm really sorry but we cannot provide support for 3rd party software here, these forums are for Railway platform or product support.

Perhaps there is a forum you could ask about RabbitMQ on?

Seems like it's not working because of railway's proxy! Else it should be fine in the first place...

here

We do not expose anything on port 5672, please use the domain and 5 digit port as shown in the public networking section.

I did, still not working. What else should i change please? see screenshot

I'm on RabbitMQ 4.1.0 Erlang 27.3.3

I need the newer amqp-node version

Yes you do need the newer amqp version.

It seems they made a breaking change.

When i installed the RabbitMQ, I used the template.
Could you please tell me how I would go about updating it within railway?
Appreciate your help in advance.

Just following up on my previous message regarding updating RabbitMQ within Railway. I installed it using the template, and I’m trying to figure out the best way to apply updates or make changes to the current setup.

Would really appreciate any guidance when you get a moment.

I'm really sorry but we cannot provide support for 3rd party software, please direct questions about RabbitMQ to their forum.

Well, I did. AND they anticipated it would happen... - see attached.
PLEASE help me with this. If the proxy wasn't blocking the ports we wouldn't be having this discussion. So helping me to fix this is the least you can do.

I love railway, just want to make this work!

I'm currently using https://customer.cloudamqp.com/ and it's working correctly. Unsure how this isn't working for me when using it locally. Can you explain?

As the user in your screenshot mentioned, you need to update to a newer version of amqp-node. This isn't something we control; keeping your dependencies up-to-date is your responsibility.

Brody, help me out here.
What needs to receive the newer version of amqp-node? Is it n8n?
I ask this because my n8n is working well with cloudAMQP (from railway) but the same version or instance won't work with RabbitMQ.
So, is it an issue with RabbitMQ, N8N or the limitations of railway cuz of the proxy? I'm honestly confused and stuck mate.

I'm sorry but we do not offer support for 3rd party software, if you need help using n8n, RabbitMQ, etc, you would need to ask their respective communities.

Though I do want to clarify, the issues you are experiencing do not have any relation to the Proxy, or the platform in general, thus why we are not able to provide support.

Going to open this to our community bounty program so that a community member may help you, but feel free to open another thread if you have any railway-specific questions.

for those having same issue may use cloudamqp as their api is compatible.

using railway for everything btw, just for free api up to 20k (lemin it is 20k and same api)

plz delete if it is not allowed on forum but wanna help people stuck with that issue on n8n
