kdl-26ex553 cannot connect to server

Hello,
I have a bravia tv kdl26ex553.
I've installed serviio and it work great for one day, then I couldn't connect to the server
through my bravia tv, getting message: cannot connect to server.
I read the serviio log file and what comes to my attentin (I really not a pro) is this:
08 23:03:28,968 WARN [RepositoryView$LibraryStatusCheckerThread] Error retrieving library update status: Communication Error (1001) - No buffer space available (maximum connections reached?): recv failed


any help?

did you run out of disk space on your server?

No, all my HDDs have plenty of space, I restarted my PC and now I can connect to the server, Strange.
I did restart my PC before and it didn't help.
