How to set up a Reverse Proxy on IISv8.5 to expose seq?

I have Seq installed on our AppServer. I need to access the Seq UI over a public domain and am trying to use IISv8.5 to set up a reverse proxy to expose the UI. I currently have a domain already which points to the IP of the app server. I have a wild card cert for *.mysite.com and have added SSL bindings to the seq.mysite.com domain. I have also installed ARR3.0 and setup the reverse proxy rules: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="ReverseProxyInboundRule1" stopProcessing="true"> <match url="(.*)" /> <action type="Rewrite" url="http://0.0.0.0:5342/{R:1}" /> </rule> </rules> <outboundRules> <rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml1"> <match filterByTags="A, Form, Img" pattern="^http(s)?://0.0.0.0:5342/(.*)" /> <action type="Rewrite" value="http{R:1}://seq.mysite.com/{R:2}" /> </rule> <preConditions> <preCondition name="ResponseIsHtml1"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" /> </preCondition> </preConditions> </outboundRules> </rewrite> </system.webServer> </configuration> However, I get a 502 error: 502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server. Any ideas?
