Error occurred when using 1.5.0 version, enabled es.all | two es instances running on the server

[Edvision]

Error occurred when using 1.5.0 version, but it's running fine when I use 1.1.0 version. I have two es instances running on the server, I think this is the root cause of the error.

Command: ./elasticsearch_exporter --es.uri https://USERNAME:PASSWORD@es-host1:9200 --es.all --es.ssl-skip-verify

Error info:
