+Subject: [PATCH] reverseproxy: fix upstream scheme handling in command (#5088)
+
+e338648fed3263200dfd6abc9f8100c6f1c0eb67 introduced multiple upstream
+addresses. A comment notes that mixing schemes isn't supported and
+therefore the first valid scheme is supposed to be used.
+
+Fixes setting the first scheme.

+fixes #5087
