Thanks.

As your posting above implies your debug message confirms a received message - but the message cannot be received, because the curl command doesn’t work …As per your advise I’ve git pulled, restarted mirror - but get same error message as before.
The curl command is bad or the URL doesn’t work.
I don’t know why and have no idea how to figure this out…Screen input- and output as follws:

@rkorell do curl -v
-
curl --v --header "Content-Type: application/json" --request POST --data '{"notification":"SHOW_ALERT","payload":{"message":"fribble"}}' http://localhost:8080/doorbell curl: option --v: is ambiguous curl: try 'curl --help' or 'curl --manual' for more information -
@rkorell not double dash
just trying to figure out what the problem is
maybe curl version -
@sdetweil OK
this is curl --version :-) (just successfully trial&errored)curl --version curl 7.88.1 (aarch64-unknown-linux-gnu) libcurl/7.88.1 OpenSSL/3.0.15 zlib/1.2.13 brotli/1.0.9 zstd/1.5.4 libidn2/2.3.3 libpsl/0.21.2 (+libidn2/2.3.3) libssh2/1.10.0 nghttp2/1.52.0 librtmp/2.3 OpenLDAP/2.5.13 Release-Date: 2023-02-20, security patched: 7.88.1-10+deb12u12 Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 pop3s rtmp rtsp scp sftp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS brotli GSS-API HSTS HTTP2 HTTPS-proxy IDN IPv6 Kerberos Largefile libz NTLM NTLM_WB PSL SPNEGO SSL threadsafe TLS-SRP UnixSockets zstd -
@sdetweil because it doesn’t work on windows either this is most likely not a version but a command or URL thing …

just trying to figure out what the problem
Dear Sam,
I caught it …
The Windows command is not working for other reasons - doesn’t matter…
The curl on MY Pi doesn’t work because - for some strange reason the resolving of “localhost” doesn’t work ???Figured this out by using another linux client (Macbook) and therefor using IP address of pi remotely - which worked instantly.
And trying this locally on Pi with IP adreees does the job as well.
Thanks again for your help!
Regards,
Ralf -
@rkorell weird, it works on windows for me
i just copy/pasted from the repo and
changed the address and port at the endi can do it on the same machine or across the network to other machines
-
@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
ping localhost
should work
-

ping localhost
should workYes, 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=5 ttl=64 time=0.031 ms 64 bytes from localhost (::1): icmp_seq=6 ttl=64 time=0.039 ms ^Z [1]+ Stopped ping localhostthanks anyway,

@rkorell so, its a curl problem… weird…
but its using ipv6 (::1 is the ipv6 version of 127.0.0.1) -
@sdetweil said in Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream:
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 definedon my amd host it is
127.0.0.1 localhoston my pi it is
127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback -
@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 :-(Ralf
-
@rkorell weird
-
@sdetweil :-) indeed
-
@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…
Regards,
Ralf -

@Cr4z33 OH…
All the best!Ralf
