Heard Messages count not updating

tl;dr – Ground station message count on Airframes.io web UI stopped updating & displayed “No recent messages found.” Decoder changed from dumpvdl2 to vdlm2dec, now recent messages are displayed but Heard Messages count remains the same.

Hi all,

I originally set up an ACARS feeder, and a few hours later changed to VDL. I didn’t notice any issues initially, only a few days later when I noticed the message count for my linked ground station was not updating. I’m wondering if someone can tell me if the issue is with my config?

Thanks in advance!

Timeline

  1. Set up ACARS feed, then change to VDL. Originally using acarsdec (station IDs: 237339489, 237339490, 237339491) then to dumpvdl2 (station ID: 237339492). Total duration: <2 days

  2. A few days later I noticed that Heard Messages had not changed, and when I clicked on the Receiver in Airframes.io Dashboard, under Recent Messages displayed “No recent messages found.” error message. Duration <22 days

  3. Yesterday, disabled dumpvdl2 & set up vdlm2dec. Configured new feed information (e.g. feed.airframes.io:5552 → feed.acars.io:5555) and retained Station ID.

  4. Ground station is now showing recent messages, but message counter has not changed.
