1. the default method for health check is HEAD see https://github.com/citrusframework/citrus/blob/3c5d8052e581d895bb360d5c2fef8205af024972/core/citrus-base/src/main/java/com/consol/citrus/condition/HttpCondition.java#L46
2. You should probably increase the timeout Given HTTP request timeout is 60000 ms
