Hey guys,
I really need your help as I'm stuck at this moment.
I'm trying to configure Webvpn to router C881G-4G-GA-K9 with IOS 15.4(3r)M1.
I'm able to download the package update from the router but on the next step it's failing with the error in the subject.
Here is full error:

Please help as I'm not sure why the security gateway configuration is invalid.

Try without profile push:
no svc profile SSLVPN_PROFILE
I know this functionality cause issues for me. It came fairly recently, and it comes with some limitations. Also check your AnyConnectLocalPolicy.xml file (located under C:\ProgramData\Cisco\Cisco AnyConnect Secure Mobility Client), for BypassDownloader option.

Hi @Milos_Jovanovic ,
Thanks a lot, I tried that earlier, unfortunately is not working, same error again.
Regarding the AnyConnectLocalPolicy.xml, what should be the correct configuration for macOS?
Thanks

There is no right or wrong configuration, there is only what suits you or not.
I configured VRF-aware AnyConnect (over IKEv2, not SSL) earlier, and I know there are some limitations when using router as compared to ASA. For this purpose, certificate on the router needs to be trusted by the client, and, at that time, profile push was not supported. For this, BypassDownloader needed to be set to True, which later causes issues with other VPNs. Later, profile push capability came, but again with some limitation (I believe it was related to profile naming).
Try going through these config guides, if you haven't already:

Hi @Milos_Jovanovic ,
Many thanks for your reply.
I tried the BypassDownloader without any success. I went through the second link and try also few things, without success.
The first link I used as reference for this configuration so every step is done
Still on same error.
Thanks

If you followed these guidelines, you did everything you should have done. Next step is to open a TAC case, they should be able to tell you what is worng with the configuration.
