Login Failed after Java Update

Hi Folks,

Having problem’s logging into Designer today after a Java update.
Accessing the gateway via its IP on the web browser and clicking Launch designer.
Then it prompts me to login.
On login attempt in red it says, login failed, please try again.
Error message says:

GatewayException: connect timed out
caused by SocketTimeoutException: connect timed out

Ignition v7.9.8 (b2018060714)
Java: Oracle Corporation 1.8.0_181

When trying to launch a client, I am getting an :
Error Launching
error launching application:
HttpResponseException: 404: Project
“(Project Name)” does not exist.

Only thing I changed today was updating Java when prompted.
Version of Java I am now using is Ver. 8_181
Gateway has not been updated and is on Ver.8_171
1 of my colleagues has updated Java also and is experiencing the same issue.
Few others have not and no problem has arisen.
I attempted to delete the java cache on my machine but no joy.
Maybe it is as simple as deleting the cache on the gateway side, or updating Java to _181?
Any help would be greatly appreciated.

Issue found not to be related to Java Version.
Redundancy Setup caused issue’s.
Investigating cause of issue.
