SD-WAN some sites give me the error the IP has changed, log in again

[hiddenhack]

Hi,
since I configured SD-WAN so as to be able to exploit multiple internet providers,  with some sites, the message is returned to me from the site "Your IP has changed so please log in again" I assume it is due to the fact that the IP with which I connect to the server changes after a few moments of logging in. How could I solve it? Thank you so much for the support

Hi @hiddenhack,

Was there a failover between your wan interfaces? Are you using dynamic or static IP address for your wan interfaces. Is you SDWAN configured as active/passive or load balancing?

I use static IP address for wan inrefaces. SDWAN is configured as in figure. 

Maybe this could be the problem. Maybe I shoul configure it in "Session" or "Spillover" mode?
