Clear your cache by telling systemd to flush it. Most of what I found online tell me to do service nscd restart, reload or do nscd -i hosts. This is best practice to always keep on removing kind of cache for the always good experience.
For every distribution, you need to launch Terminal. It depends which service you have in your distribution and if the system enabled it by default.
Any kind of work around is fine as well. The procedure is the same for almost all Windows systems. The removing of cache is called flush. There is no notification when the process finishes. Step 1 — Launching Windows command prompt console Press the Windows+R key combination in order to open the Run dialog box. Sometimes bad results will be cached and therefore need to be cleared from the cache in order for you to communicate with the host correctly. If you are running Ubuntu, everything is already set up and ready to go. However, none seems to flush the cache. A quick way to clear the cache is to restart this daemon. You can use any number in place of 150, which is basically the number of entries that dnsmasq can cache. Clearing cache is an easy and quick process. However, you can append another command to change that.

When I configure my webserver and change the records, I have to wait the time configured in the ttl of the specific record. I know, that I can change the ttl to a lower value, but the default value is 3 hours, so i have to wait until the time's up. And here's my question: How can I refresh it manually.

So there is nothing you can do, unless you run your own caching resolving nameserver. I don't think that provider linux clear dns cache public resolving name servers let you flush their cache. So there is nothing you can do, unless you run your own caching resolving nameserver. Some providers allow a forced refresh, for example opendns. There are also routers with an integrated nameserver which has to be flushed. If you want to be able to react more quickly to emergency situations, set it lower.
