Hello, we have a big problem since yesterday where...

Hello, we have a big problem since yesterday where Session no more launching because we found that internet navigators cancelled the download of ica file. We connect with netscaler, Storefront and Citrix Daas. Some of you saw a similar problem ? Thanks
We found that the cookie 
CtxsClientDetectionDone
is impacted. When we delete this cookie, connexions are working because ica file is downloaded and we have to clic on ica file to launch desktop.

What about using the Citrix WebExtension?
l
Same problem, we tried with support.
When I try connexion directly from storefront load balancing url, I haven't the problem, so the problem seems to be on netscaler.
We will patch it in 64.29 and reboot it tonight and show after reboot if it's better or not.
We are waiting of netscaler support team now.

there is a known issue with storefront 2607 and mac workspace where the ica file doesn't have an extension but this sounds different
l
have storefront 2402 CU3
and we do not touch anything on our environment.. issue appears suddenly.
😞
and ioc scanner says not compromised because I thnik of this.
m
did workspace app update?
l
no
it's very strange.. will see tonight after reboot of netscaler.
m
and it's doing it with all the browsers, chrome and firefox?
or just workspace app?
client detection cookie sounds like it could be related to the other issue, do you have client detection turned off in storefront?
l
yep all browser but sometimes if user never connect firefox because he's using chrome, it can work with firefox. But on chrome, we have to kill the cookie or go in private mode to download ica file and lauch it because de detection of CWA is not appearing.
Connexions are randomly working directly through CWA configuration.
do you have client detection turned off in storefront -> I forgot where I can found this.
m
I haven't heard of this exactly but it sounds similar to a known issue where it can fail with detection turned off in storefront
I would open a ticket because there is a fix for the later version
l
we have a ticket opened and storefront team says eveything is ok and opened new case to netscaler team. We are waiting of first answer from support. We already will patch tonight and reboot netscaler. Maybe per miracle it will work again 🙂

Are you on 13.1 or 14.1? Assume 13.1 since you mentioned 64.29
l
13.1 b64.24 and this night 13.1 build 64.29 after the upgrade
We found the issue: was dns resolution issue on netscaler.. we think that netscaler used his dns cache because dns server had no response and after rebooting no more connections were possible until we change dns to server that responded.
