Hi @stealthanthrax this change produced some regression - does it work on Raspi? With this patch I get communication errors between susi server and susi linux:

With patch evey 10s sec the following warning on the server side

Apr 16 13:51:11 burischnitzel start.sh[14160]: 2019-04-16 13:51:11.146 WARN org.eclipse.jetty.http.HttpParser  - Illegal character 0x16 in state=START for buffer HeapByteBuffer@626b966c[p=1,l=319,c=8192,r=318]={\x16<<<\x03\x01\x01:\x01\x00\x016\x03\x03\xB2{\x8f\xBd\x80\x1a\xA9...\x02X>.\xC4egm{\xC7\xC5\x82j\x9d1>>>tent-Type: applic...\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00}

and on the susi linux side:

...

This is on my desktop, not a raspi, though. Do you have an explanation for that?

norbusan commented 5 years ago

It seems that something in the encoding of the request is going wrong.
