Over the last month or so, I've seen an increase in these error messages, with Anteater and Weasel being the most common. I have a wired connection, an Open NAT type, and the recommended ports forwarded via my router. To verify that it isn't a lower-level hardware issue for networking, I have run ping tests using both IPv4 and IPv6 to google.com and bungie.net and experience no loss or delay of packets when the errors occur. Not sure where to go from here in terms of troubleshooting, but it is affecting my ability to play end game content with random disconnects.
