Node-red v0.18.7 was working fine until this morning, however now it will not start anymore.
Running it on my raspberry 3B+ with Node-red start will give this error:
11 Feb 11:49:54 - [info] Starting flows 11 Feb 11:49:54 - [info] Started flows 11 Feb 11:49:54 - [red] Uncaught Exception: 11 Feb 11:49:54 - Error: listen EADDRINUSE 0.0.0.0:1880 at Object.exports._errnoException (util.js:1020:11) at exports._exceptionWithHostPort (util.js:1043:20) at Server._listen2 (net.js:1271:14) at listen (net.js:1307:10) at net.js:1417:9 at _combinedTickCallback (internal/process/next_tick.js:83:11) at process._tickDomainCallback (internal/process/next_tick.js:128:9)
Rebooting the pi didn't solve the problem.
Someone an idea what could be the problem?
