matchclass
is deprecated in favor of class. Can you try the same, but using 
class
as follows:

if { [class match [string tolower [HTTP::host]] ends_with data_group] } { reject }

and see if that makes a difference?

hi.. i have now updated the irule to the following: if { not [class match [string tolower [HTTP::host]] ends_with data_group] } { reject } but this is still not working for requests that also include a subdomain. the request being sent from the server is api..xx/, but this fails. if we open a browser on the server and go straight to https://, it gets through. this indicates that at least some parts of the irule is working, but it fails to send a request through if it is including a subdomain as well...unless im missing something here also, as this is a proxy, it uses 8080.. does this get attached to the host header? if so, it will probably cause issues with "ends_with"
