Bridge not working with a specific kind of topic

[Anzal-calixto]

Here is the my broker configuration bridge file.

address broker.emqx.io:1883
#bridge_cafile /etc/mosquitto/certs/ca.crt
#bridge_certfile /etc/mosquitto/certs/client.crt
#bridge_keyfile /etc/mosquitto/certs/client.key
topic home-15646/# out 0
topic home-15646/# in 0

instead of this if give home/# the bridge will work fine.

also its giving a broken pipe error.

try

address broker.emqx.io:1883
#bridge_cafile /etc/mosquitto/certs/ca.crt
#bridge_certfile /etc/mosquitto/certs/client.crt
#bridge_keyfile /etc/mosquitto/certs/client.key
topic home-15646/# both 0

But it feels like this might be something else.

tls settings good?

[Anzal-calixto]

Tls settings are working fine when I try with emqx broker it's working but if I am connecting to mosquito broker it's not bridging

[hardillb]

Try wrapping the topic in quotes

address broker.emqx.io:1883
#bridge_cafile /etc/mosquitto/certs/ca.crt
#bridge_certfile /etc/mosquitto/certs/client.crt
#bridge_keyfile /etc/mosquitto/certs/client.key
topic "home-15646/#" out 0
topic "home-15646/#" in 0

thanks @hardillb i tried using above method it doesn't seems to be working

[Daedaluz]

I think there should be a "both" variant to "in" and "out", try that instead of in and out separately.

[Anzal-calixto]

1719215263: Error creating bridge: Broken pipe. 1719215294: Connecting bridge (step 1) home_connection-15646(test.mosquitto.org:1883)
@Daedaluz tried that still gives the same error

[Daedaluz]

What does emqx logs say?

[Anzal-calixto]

this is the log for emqx

[Daedaluz]

that looks like logs from mosquitto.

[Anzal-calixto]

@Daedaluz In my setting my local broker is mosquitto and when i am trying to bridge this local broker to a mosquitto broker thats when it gives the error and bridge is not being connected. If i try to bridge it to an emqx broker bridge is working fine. my cloud broker is a mosquitto broker and the emqx broker is an open broker

[Anzal-calixto]

@Daedaluz @hardillb any suggestions

[ckrey]

@Anzal-calixto "home-15646/#" is not a valid topic filter (because the # is not at the end).

Please correct to home-15646/# which is probably what you intended

[ckrey]

Can you try with a more recent version of mosquitto (2.0.18)? 2.0.11 is 3 years old

[Anzal-calixto]

@ckrey i tried home-1546/# it was also havig the issue i will update mosquitto and try again

[Anzal-calixto]

hello @ckrey i am using debian 11 it seems the latest version that is available for dedian 11 is 2.0.11

[ckrey]

Setting up a brigde to test.mosquitto.org:1883 works well with mosquitto 2.0.11 and 2.0.18

Please show us your complete config with bridge to test.mosquitto.org (all your snippets above show the config with emqx)

[Anzal-calixto]

sure here is the settings

address test.mosquitto.org:1883
