Hi,
lately we started proxying our Jira instance using Apache and we noticed an error, when trying to create a new sprint. It says "error bad request".

Here is a screenshot from chrome

And here is Tomcat config
<Connector port="8181" maxThreads="150" minSpareThreads="25" connectionTimeout="20000" enableLookups="false"
maxHttpHeaderSize="8192" protocol="HTTP/1.1" useBodyEncodingForURI="true" redirectPort="8443"
acceptCount="100" disableUploadTimeout="true" bindOnInit="false" scheme="http"
proxyName="<ourdomain>.eu" proxyPort="443"/>
I tried adding a certificate to jre cacerts - not helping.
Do you have any idea how to fix it? Google says nothing relevant and I've been fighting with this problem for 2 days straight now.
