You need to add diffie-hellman-group14-sha1 to your ssh config to connect to the switches for each switch you will be connecting to.
To edit the ssh config go to C:\Users\[your user here]\.ssh\ then open the config file with a notepad software (it does not have a file extension so double clicking will not know what to open it with)
In our case your ssh config file should have these lines in it:

Host 10.10.50.101 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.101 
Host 10.10.50.102 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.102 
Host 10.10.50.111 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.111 
Host 10.10.50.112 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.112 
Host 10.10.50.113 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.113 
Host 10.10.50.114 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.114 
Host 10.10.50.115 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.115 
Host 10.10.50.116 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.116 
Host 10.10.50.117 KexAlgorithms +diffie-hellman-group14-sha1 User manager Hostname 10.10.50.117

Generic

SSH to any of the switches on our network as the manager user using the password in LastPass:

Access01-Access07 - 10.10.50.111-10.10.50.117
Core01-Core02 - 10.10.50.101-10.10.50.102
