We have a php application that is using the SOAP api to connect to Salesforce.  We have noticed intermittent issues with connecting to SF, which throw the error message “Could not connect to host”.  Following the stack trace it seems to be having issues at login with https://login.salesforce.com.  When the errors are occurring we can still connect to SF via a browser using the same user/pass, and other integrated solutions seem to be able to connect with the same user as well.  Eventually the connection to Salesforce corrects itself, but this happens without any updates on our end, so we are at a loss as to the root cause. 

We have checked allowed ip ranges for the user profile associated to the user, but those don’t seem to be a problem.  We have also checked to make sure the api calls aren’t maxing out and at the time of the last occurrence, we were at approximately 10% of our max.  It seems to be very similar to https://developer.salesforce.com/forums/ForumsMain?id=906F00000008r3jIAA, but that issue doesn’t seem to be answered fully.

Any help would be appreciated. Right now we have customers logging into our application and the reliablitiy is constanly in question because of this problem connecting to Salesforce. We never know when it will happen or how long the problem will last. About a week ago, we had almost 24 hours when our application could not connect. Again, with no changes on our end this problem just starts and stops.

Thanks,
