Gas price estimation failed due to network error

[scottreg]

Hi Everyone,
Hoping I can get some guidance on this issue. I did a search and couldn't find anything explaining what happened and how to fix it. If this is not the correct place for the issue please let me know where to go so, here it is...

I have some ETH in my Metamask wallet and I am attempting to send it to any one of several exchanges and as soon as I hit the Max button or populate the amount with any number I get the following error in a red box and I'm not sure what to do.

"Gas price estimation failed due to network error."

I tried the different networks to see if is a differnt one than Ethereum Mainnet, but it's not.

Thanks in advance for any help!!
