jxbrowser 7.15: SOCKET_ERROR "Only one usage of each socket address (protocol/network address/port) is normally permitted"

we are using JxBrowser 7.15. Has anyone experienced following error? "Only one usage of each socket address (protocol/network address/port) is normally permitted" And maybe have a solution/hint for me ?

we regularily get this SOCKET_ERRORS using JxBrowser 7.15. (several times a day) There are several JxBrowsers running in parallel there, but in separate java processes.

in the log is: "TCP connection to 127.0.0.1:62787", so to itself. I know this is how JxBrowser is communicating, but I want to ask if you know something about this in version 7.15 ? Or is maybe some parameter setting wrong in my programming I checked the machine and it seems no other application is using 127.0.0.1:62787 in this example.

Here the log lines: 8:27:19.203 DEBUG [Chromium] [15296:9524:0504/082719.203:ERROR:connection.cc(183)] ::connect() failed: SOCKET_ERROR: Normalerweise darf jede Socketadresse (Protokoll, Netzwerkadresse oder Anschluss) nur jeweils einmal verwendet werden. (0x2740) 8:27:19.203 DEBUG [Chromium] [15296:9524:0504/082719.203:ERROR:connection.cc(138)] Failed to set up a TCP connection to 127.0.0.1:62787
