Hello Kirill,

in 0cf70a6e we already migrated the NEO URI concatenation to the recent format used by WCFS. Unfortunately we missed separating the address (IPv6 + port) of the master nodes from each other. Without adding the separator , between them, WCFS doesn't work with NEO clusters which have multiple master nodes, because NEO/go can't split the different master node addresses.

This is necessary for kirr/neo!2 (merged).

Due to the reasons mentioned in !1308 we can't add automatic tests for this fix now. I therefore created a dedicated instance just to test this fix manually. A bit overkill for such a small fix, but anyway I could verify now that this fix works. If needed I can provide access data for this instance in private.

Best, Levin
