Are you submitting the form via a Dispatcher or direct AEM Server FQDN? If so, hope you have set the correct rule for allowing attachments in the dispatcher config.

Not sure how this worked for the first time, but usually intermittent issues such as this one would point to a problematic config on the LB/Webserver side, if direct IP/FQDN works.

Thank @Pulkit_Jain_ your ans

Thank @Pulkit_Jain_ your answers, now the form submitting via a Dispatcher, you have document talk about set the correct rule for allowing attachments in the dispatcher config ?

Pulkit_Jain_ · 5/12/21

Good to know its working now! You may need to add this rule in the dispatcher config: # allow AF attachments /0200 { /glob "*/tmp/fd/*" /type "allow" }

Hi @Pulkit_Jain_, i have mistake with info my server, Now my team use using AWS Cloudfront, not Dispatcher for AEM. Anything else i can try? Thank you!

Pulkit_Jain_ · 5/20/21

Please confirm if the form works as expected when you hit the server directly- via FQDN/IP bypassing the CDN? We will troubleshoot accordingly.

danhdinh · 5/20/21

Thank @Pulkit_Jain_ i will try it

danhdinh · 6/9/21

Hi @Pulkit_Jain_, I debug more to see maybe problem by load-balancing of server. When i click submit button the form will post Attachment to Server-1 then trigger submit form to Server-2. You have anything solution to can fix it? Thank you so much

Pulkit_Jain_ · 6/9/21

@danhdinh I have seen this issue previously. Could you please add the following property in the “dispatcher.any” file - /stickyConnections { /paths { "/content/forms/af" "/tmp/fd/af" } } OR enable sticky connection on LB side. If you need immediate help on this one, please raise a ticket with support.
