Backup of postgres database giving ssl error - postgresql

Question

I have been using using DBeaver and I got a new laptop. With a fresh install adding the postgres remote database exactly as it is in the other computer.
I can see all the tables and data in the database. I just cannot take a backup.
When I right click tools->backup and I click start (same process works on old laptop) I am getting the error below. If I do this with my local dev database it works fine as expected. I can do a backup on my laptop both directly before and directly after trying on the new laptop.
C:\Program Files\PostgreSQL\10\bin\pg_dump.exe --format=c -n public --verbose --host=compute-1.amazonaws.com --port=5432 --username=elkjlkjkjyb d5kjhkjhjkht5

UPDATE
I believe this has to do with a large query problem instead of a ssl problem. I did an insert with 50 rows and no problem. As soon as i go over a certain number of characters it seems to break connecting to the server. Also I believe the pg_dump is a problem because the query it tries to do is a very large query. This is a local problem because it doesnt happen on my other laptop.
Probably some max setting in Postgres 10.5-2 or JDBC. My old laptop has the same JDBC version as my new one. Old laptop has Postgres 10.4-1 though.

Answer 1

So this turns out not to be related directly with Postgres.
I have a MSI GS65. It has a hardware network driver called killer network.
The driver has settings you can modify. One of those setting is to optimize network speeds. It seems that this setting will drop larger connections. When I am doing a backup or a large query through dbeaver, it drops the connection and stops the backup/query.
Took me 2 years to find this issue. I hope this helps any devs with a MSI computer with network issues.
