I'm working on a site that is load balanced between two servers, and I am using Umbraco Forms for their Support form. This is the only form on the site, but users are seeing an inconsistent issue where every now and then a user will get a 500 error when submitting the form instead of being taken to the Success page, as defined in the form's settings.
The form entry is saved and visible from the backoffice, and my notification workflow goes out without issue. I've tried disabling the workflow, but that had no effect. I've also tried keeping an eye on various cookies (especially ASP.NET_SessionId) as I figured that might be arguing with the two load-balanced servers somehow, but I've yet to find any solution there either.
Umbraco Forms 500 Error on Load-Balanced Site
Hello all,
I'm working on a site that is load balanced between two servers, and I am using Umbraco Forms for their Support form. This is the only form on the site, but users are seeing an inconsistent issue where every now and then a user will get a 500 error when submitting the form instead of being taken to the Success page, as defined in the form's settings.
The form entry is saved and visible from the backoffice, and my notification workflow goes out without issue. I've tried disabling the workflow, but that had no effect. I've also tried keeping an eye on various cookies (especially ASP.NET_SessionId) as I figured that might be arguing with the two load-balanced servers somehow, but I've yet to find any solution there either.
Anyone run into a similar issue?
Hi Ryan,
Have you seen this package for running Umbraco Forms in a load balancing environment.
https://our.umbraco.org/projects/website-utilities/umbraco-forms-cache-refreshers-for-flexible-load-balancing/ and you can see we have fixed some LB stuff in Umbraco Forms 4.3.0 http://issues.umbraco.org/issue/CON-895
Hope this helps,
/Dennis
Looks like that did the trick! Thanks!
