Step 1: Provide useful / actionable information when asking on a public forum. I.e.:

• What kind of SSO did you configure / enable? You say "external SSO", but the configuration in share-config-custom.xml also uses an "external-auth" section when Kerberos / NTLM are being used, so it would be ideal if you could clarify which subsystem you have enabled...
• Did you properly configure the "Remote" config section, especially the endpoints therein, as described in the official documentation? WIthout using the correct endpoint (i.e. /alfresco/wcs/) and making sure to use sessions as well as "external-auth" set to true, you may encounter potential issues.
• Are you by any chance using a proxy / web server in front of Alfresco which may be dropping the session, or - in case of a clustered Alfresco - be redirecting the request to a different backend (session stickyness is a must in this use case)?
