Can't connect to NAS using MacOS Monterey in Safari

Greetingsohn Williams,

Thanks for using Apple Support Communities!

You can use Connect your Mac to shared computers and servers, and here's how to check the settings on your Mac:

"Connect to a computer or server by entering its address

1. In the Finder  on your Mac, choose Go > Connect to Server.
2. Type the network address for the computer or server in the Server Address field.

For information about the correct format for network addresses, see Network address formats and protocols.

3.Click Connect.

4.Select how you want to connect to the Mac:

• Guest: You can connect as a Guest user if the shared computer permits guest access.
• Registered User: Connect to the other Mac using a valid login name and password. If “Only these users” is selected on the other Mac, make sure the login name you’re using is on the list of allowed users.
• Using an Apple ID: Connect to the other Mac using an Apple ID. You must be set up in Users & Groups preferences with this Apple ID, on both this Mac and the other Mac.

If necessary, enter your user name and password, then select the server volumes or shared folders.

5. To make it easier to connect to the computer in the future, select “Remember this password in my keychain” to add your user name and password for the computer to your keychain."

We'd want to rule this out first.

Next step would be to work with Synology. You'd want to go through any setting that would be needed, and confirm that it's compatible.

Take care!

This doesn't look like a Synology issue and more of a Mac OSX issue. All other devices can get to the Synology NAS except for my MacBook Pro.

I'm having the same issue with my DS1819+. I can get to the NAS using every other method such as PC, iPad, iPhone, etc. Just can't get to it from my new MacBook Pro M1 Ultra! It was working for a long time and then all of a sudden this morning, when I power up my Mac it won't mount the network folders nor can I browse to it within Safari or Chrome.
