Library.ybd is still in use?

Hi, I'm using Yacreader on Ipad and I've created a comic database in Raspberry Pi for accessing the comic files.
I'm not able to access the remote database.
When I try to start the library at YACreaderLibraryServer I'm getting a message "library.ydb76fddb20' is still in use, all queries will cease to work". See below.
Library is not in use as it has just started to run.
Do you have any idea on why this can be happening?
Thanks for any feedback!

I'm not able to access the remote database.

What is the exact problem? That error message has nothing to do with it.

I think the server hasn't completely started, or it is in another port different from 8080.

When I try in another terminal this:
I get this response:

I add some information

When I run
$ sudo lsof -i -P -n | grep LISTEN

The only row that mentions YAC is this
YACReader 2700 root 5u IPv6 104856 0t0 TCP *:44163 (LISTEN)


Does that mean that Yac is running in port 44163 instead of 8080?
Should I set that port in the ipad?
Why does it use that port instead of 8080?
Thanks

Yeah, the problem is the port. By default it tries to use 8080, if it find another process using that port it starts to listen to another port randomly, that's where 44163 comes from.

In this situation the right thing to do is to set another port so it will always use it. www.yacreader.com/forum/support-linux/58...erlibraryserver-port

IIRC 9.5.0 has the option of setting the port when you launch yacreaderlibraryserver, -port or something. It is probably better to use this approach.

Yes, I edited the YACReaderLibrary.ini file, and added the port line under "listener":

and now it works again in port 8080. I don't know why it didn't use this port by default, as no other process was using it. But anyway it works great now, so thank you!
