Please, tell me what is the reason?

Unknown tag is the reason. Do you have protocol documentation?

Anton,
I act as an end user, unfortunately I do not have documentation on the protocol.
found only this guide http://base.galileosky.com/articles/#!docs-publication/galileosky-7x-user-manual

correctly I understand that the current protocol is not supported by the traccar server?

The protocol is supported, but some new parameters are not.

http://base.galileosky.com/articles/#!docs-publication/galileosky-protocol
0xFE Tag showing the presence of extended tags
Extended tags are sent as tag data 0xFE

Unfortunately the link doesn't provide any details on how to decode it or how to determine the length.

Good afternoon, the support engineer recommends that you apply for information on the protocol at the following address:
http://base.galileosky.com/articles/#!docs-publication/galileosky-protocol

where the protocol and its specification are described

Have you done that?

I'm not sure if there is enough information on the given page for the manufacturer's protocol to work and
your protocol for processing. as I understand it, this information is not enough for you to adapt to your implementation and support of equipment with this protocol?

Correct, as I said previously it doesn't have enough details about the extended tag.

the manufacturer is ready to get involved in solving this problem in the new year. I hope they are interested in their devices being distributed in alternative software products.

Dear

I contact the GalileoSKy 7x manufacture regarding to 0xFE and they mentioned to this link -> Packet protocol tags

BR

It still doesn't explain how to determine the length for the whole field. How do we know when it ends?
