Looks like there is some problem with decoding. It doesn't seem like correct protocol.

Hi Anton,
Thanks for your fast reply, today i'm not have logs strange...and i've idea to add filter.distance & filter.duplicate...and all work fine not have any log strange....because all have fine so i try to disable logs with "logger.enable false"...but i'm found, if i send command to device like "STATUS#", PARAM#, RELAY,0#" not have reply on the web notification...last before i disable log the reply always receive on the web notification. so i try remove log enable false from traccar.xml and i try to restart....and i found that's log

If you don't have any logs it means that your device doesn't send anything.

I'm mean not have any log strange like that's log....just normal log as usual

Then I'm not following what the question is.

my question is what happend with my traccar sever about that's log. that's log does not appear before i'm add log enable false then i remove it

Something or someone is sending some data to the port. That's what log says.

sory maybe you confuse with my mean...because my english is bad...so i try to tell you the
chronology :

1. until today morning my traccar is normal...i've 3 device connect to my traccar server...just have normal log report from that 3 device
2. I try to look report route by web...and i'm found many report with same coordinate with different time...so i add filter.distance....that's work fine
3. I try to add filter.duplicate (that is just try)
4. all work fine...just have normal log as usual
5. i'm feel to disable any log maybe can reduce the cpu & ram resource...so i try to disable log with add log.eneble false...this is work fine...the log have stop create
6. I'm try send command by web to device RELAY,0# to stop engine...the command already send and work fine, but not have any reply on web notofocation
7. so i think disable log make to stop notification on web, so i remove log.enable false from traccar.xml...i start the traccar... and the log show very fast any error like i'm paste on the top
8. now...i'm confused..what happend? because last before just normal not have strange log ?

Disabling logs doesn't affect any Traccar functionality.

oh.... what does it mean the problem is not from my server?

I don't understand what the problem is.

oh...ok Anton...thanyou for your very fast respons... i will try to look again...hope you have nice evening :)

just inform...now after i've already remove log.enable false.... i've try send some command to device and have notofication reply on the web

OMG......Anton...I just realized what you mean, that maybe someone is trying something....hahhaa...ok2 thankyou anton....regards
