Hello All,
I'm facing an issue related to Alteryx Gallery. My users complained that they can't access the gallery. The gallery portal is getting down frequently every day and i don't have a clue what might be going wrong. I first noticed this error in early week of June 2020 but since last 3 weeks it is happening consistently almost every day. Few days the portal would be down only two times while other days it's more than two times going down.
We ensured we have no issues with the CPU, Memory and space and Alteryx recommendations are met.
AlteryxServer Version 2019.2.10.64688
CPU: 3.00 GHZ (2 processor) 8 cores ,
Memory: 128 GB
705 GB Disk space available

Diagnose done so far: Whenever the gallery portal goes down; one of below message is what I can see on the browser
- {"data":null,"exceptionName":"AlteryxServiceException","innerExceptionMessage":"","message":"Error receiving data: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.\u000d\u000a (10060)"}
- An unknown error occurred during authentication with your Windows credentials
I tried looking at the Service Log & the Gallery logs and the below is what i find but I'm not able to decode it 😞 The places where i have masked in the error log below is the IP of the user invoking the app request and the Alteryx server. There is also socket time out error in the logs.

Whenever the user complaints of the portal being down, I goto the services.msc to find the AlteryxService.exe Status. My initial assumption was that if the portal is going down then one of below services could be down but this is not the case. All Alteryx related services seems to be running OK.
- AlteryxService.exe:
- AlteryxCloudCmd.exe
- mongo.exe
- alteryxService_WebInterface.exe
- MongoController.exe
So I simply restart the AlteryxService.exe and the Gallery portal becomes up and accessible. Since it's happening every day multiple times, so, I have created a batch script and scheduled it to starts the AlteryxService .exe to avoid the above situation happening. As of now the iam simply restarting it few times in a day irrespective of AlteryxService.exe status. However, iam looking for a permanent fix.
Also did a telnet to my Alteryxserver and the port it returned blank
When the gallery portal goes down, i also find it down on the Alteryx Server machine as well.
We have also raised a support ticket with AlteryxSupport a week back and still awaiting their responses. I am hopeful someone in our Alteryx community would have encountered this and would be able to assist me how we can avoid it.
Thanks ahead for your time and support.
