Connection problems from Twilio to SMS Autoresponder

[Mark Stark]

I am getting intermittent "Error 11200 - HTTP retrieval error": when someone responds to an SMS text from Twilio. Sometimes it works fine, but other times it fails. When the error happens, the SMS Autoresponder doesn't work. I used the Messaging Services configurations. Any ideas what I can change? Should I uninstall Messaging Services and install one of the other apps? Thank you

Good day @Mark Stark

Please refer to the following article for above error: https://www.twilio.com/docs/api/errors/11200

Hope that answers your question.

I'm sorry, but that does not answer my question. I already read this article from Twilio. It says that the problem could be a web server. However, the web address is my SF site, which has not experienced any interruptions. I experienced this error at the same time I was using Salesforce without any problems. It is happening 50% of the time. I believe there is a problem with the Autoresponder setup. My question is if one of the other options besides Messaging Services would be more reliable. Thank you

Good day @Mark Stark

Would you please grant us login access to your Salesforce account and share the screen shots of the Twilio message setup so that we can review?

Looking forward to hearing back from you.

I have granted one week access for SF org ID 00Di0000000eL4T. I've attached the screenshots, it's difficult to see the whole URL, but it is: http://hkidsf.force.com/default/CnP_...nP_SMS_Handler

I originally configured with Messaging Services, since it had problems I deleted that and I'm now configured with TwiML App.

[Mark Stark]

Is there any other information you need? The URL is http://hkidsf.force.com/default/CnP_...nP_SMS_Handler. It got truncated in the post above. Thank you

Good day @Mark Stark

Sorry that we have missed this post.

We noticed that you have used the non-secure URL in Request URL. Would you please change those URLs as below and check:

Request URL : secure
FallBack URL : non-secure

However, this is all depends on the server availability. Sometimes it will take time to load when server is busy.

Please check and let us know if that resolves the issue.

[Mark Stark]

I'm sorry, what is the "secure" vs. "non-secure" URL?

[Mark Stark]

I tested with the Secure URL listed first; I did not get an autorespond message via text, but my message was logged in SF. However, there was an error generated twice in Twilio (once for each site). I get the most consistent results using the non-secure URL in both the primary and backup using the Webhooks/TwiML application. Is there a way to change the Twilio timeout?

Good day @Mark Stark

Would you please share the Log details of Twilio so that we can review? Please remove the Phone numbers from the Log before sharing here.

However, you may need to contact Twilio support to see if they can help with changing the timeout.

[Mark Stark]

Here are the log details. I already tried to increase the timeout; it is 15 seconds and Twilio says they cannot increase the time.

Good day @Mark Stark

Sorry but the images you have provided is PNG and this forum does not show it in full scale. I only see a thumbnail. Would you please post this as a JPG so we can review?

Looking forward to hearing back from you.

[Mark Stark]

I think the problem was I inserted thumbnails. Here are the full-sized versions

Looking forward to hearing back from you.
