Hi i am testing BRS 2.0.4 until tomorrow. Then i am swichting back to 1.3.6cg and waiting for the next wallet without solo mining issues. Your suggestion was good ond github they told me to set a second setting in the brs.default.
With these settings am able to solo mine on BRS 2.0.4 :). It seems to be a workaround but now the developers are aware of this solo mining issue for the next wallet version and for the dymax fork.
For all other Solo miners if you want to solo mine on BRS 2.0.4 the solution is:
Make a text file called brs.properties
copy and paste following to the brs.properties file:
the brs.send...=10 setting is important. Without that setting i wasn't able to solo mine on BRS 2.0.4.
For all others use 1.3.6cg Wallet until the next Wallet for stressfree solo mining.
Now this issue for Wallet 2.0.4 is solved / you have a workaround.
