@sdetweil said in Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream:

@rkorell localhost is(always) mapped to 127.0.0.1 on the same system
which is called the loopback adapter, cause the packets never leave the system

Yes. I’m aware of this, thanks.

ping localhost
should work

Yes, do work:

pi@MagicMirrorPi5:~/MagicMirror/modules/MMM-CurlToNotification $ ping localhost
PING localhost(localhost (::1)) 56 data bytes
64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.027 ms
64 bytes from localhost (::1): icmp_seq=2 ttl=64 time=0.035 ms
64 bytes from localhost (::1): icmp_seq=3 ttl=64 time=0.035 ms
64 bytes from localhost (::1): icmp_seq=4 ttl=64 time=0.036 ms

64 bytes from localhost (::1): icmp_seq=6 ttl=64 time=0.039 ms

@rkorell so, its a curl problem… weird…
but its using ipv6 (::1 is the ipv6 version of 127.0.0.1)

good catch!
THis may is the reason, because - as far as I. know - ipV6 isn’t implemented (properly?) in my network (at least I do not have anything configured. My AVM (Fritzbox) router is ipV6 aware but I do not “use” it esplicitely …

Strange!

@rkorell can you edit your /etc/hosts
to see how localhost is defined

on my amd host it is

127.0.0.1       localhost

on my pi it is

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback

rkorell

@sdetweil Oh, yes - I remember …
interesting enough my /etc/hosts is likely the same as on your Pi - with ipV6 entries.
If I delete them, error remains :-(

@rkorell weird

rkorell

@sdetweil :-) indeed

rkorell

@sdetweil and now 3hours later more weird it doesn’t work with IP address as well.

In addition for some strange reason the enablement of the MMM-Mplayer module leads to unrecoverable disconnects of PI from network.

This currently is too much resistance to me, so sorry dear @Cr4z33 - I’m not able to dig in deeper to assist you…

Once again thank you @rkorell and @sdetweil for willing to help me!

Unfortunately real life last minute serious event had to stop me to dedicate to this matter for a long while.

rkorell

@Cr4z33 OH…
All the best!
