Yes

Content match failed

not generic error message any more, not used as it is but rather a detailed message of which element validation is failed

A special case of 1501 Clickpath action failure where the failure was caused by missing or wrong locators so mainly locator failure. The player couldn't find the element to click on but if the validation before is not set to fail then it won't be a validation timeout error. 1501 will stay the default error in case we don't want to show the details of the error to the user (as it might be an internal error/exception)

@xu_guo,

Thanks a lot! I believe these codes should also be in the documentation.

BTW, do the 97? codes also appear in synthetics?

Hi @xu_guo

Do you have any idea how to get past and fix the error 12020 - The site unexpectedly closed the connection.

There is also an error code 12006 Site Reported Unexpected, if anyone has experience with that.

12006 Site Reported Unexpected is the Chrome ERR_UNEXPECTED error. This is usually caused by an authentication issue. If you curl to the application from the ActiveGate, do you get a successful response? Often it is the case that a proxy is required to allow the ActiveGate to access the application. Or if you are already using a proxy, possibly you need to bypass it for the affected application. You can see the different scenarios available here

Hello,

We're observing "The request failed with error 12100: ABORTED", any idea what exactly this means? and possible causes?

Couldn't find any details in the docs.

 

Thanks,

"The request failed with error 12100: ABORTED" is seen where the request got aborted, and the browser doesn't provide any more details. Do you see the same in DevTools?

Hi @HannahM ,

No, we observe this error only in waterfall analysis of the synthetic executions and is intermittent with no real trend.

OK, I would open a chat in the WebUI and provide a link to monitor and if possible a Har from when the page was loaded. Thanks

Is that from a Browser Monitor or HTTP Monitor? We mention it here for HTTP Monitors

@HannahM 

Can you please tell me how to resolve the 403 error of the synthetic monitor?

The URL is getting loaded when I try in the browser, but somehow, it is throwing a 403 error in Dynatrace.

I have created RUM for this application, but no user actions are getting captured, to troubleshoot this I created the synthetic monitor which is throwing a 403 error.

Can you please help me with this?

Hi @Vaishnavi_Ubhe,

Is your synthetic running against public Dynatrace robot? Private location?

Is it running against a private location.

403 is a forbidden error. Have you added credentials to the monitor to allow it access? If you open the page from the Private location does it have access? Sometimes customers need to explicitly allow certain machines to have access using a proxy or network rules.

Hi,

I have the same behavior (intermittent as well). 

Did you found the root cause and/or a fix ?

Best regards

You're missing "1702 - The specified target window got disconnected".
