wireless networking – PC cannot connect to multiplayer games that use third party servers

This is very difficult to explain, but I cannot play multiplayer on Call of Duty: Modern Warfare or Borderlands 3. Every other multiplayer game works, and the things that these 2 games have is that they both launch off one companies platform (CoD launches off battle.net 6, and Borderlands 3 launches off Epic games) then they have to connect to another companies servers (CoD uses activision servers and Borderlands 3 uses shift servers). I have contacted all of the companies and they all blame each other, none of them have provided any working solutions. Here is what I have tried:

Ensuring both games are allowed through firewall

Using wired connection

Using wireless connection

Restarting Modem, Router

Allowing lasse.exe through firewall

Reinstalling both games

Ensuring both games and the platforms they launch from are up to date

Clearing Cache for both games

Flushing DNS

Unlinking and relinking accounts (ie. Battle.net 2 linked to Activision account)

I am unsure what else I can try, and I haven’t really found anyone online with this same issue across all games that have servers that function like this. I am starting this thread in hopes that someone has encountered this issue in the past and has a solution or someone who is more experienced in networking has a potential solution.

oracle – How to connect to specific session id & serial# ? Blocked sessions

I have blocked sessions and see which session is blocking them, having session_id and serial#. Is it possible to connect to such session? How?

Background: using V$SESSION_BLOCKERS I see sessions are blocked by each other by INSERT statements to one of two tables: _REQUEST and _RESPONSE

Blocked sessions wait event: enq: TX - row lock contention

Query 1:

insert into _REQUEST (creation_date, IS_PROCESSED, name, packet, PARENT_SKID, BATCH_SKID, retry_delay, revision, SERVICE_NAME, ttl, type, REQUEST_SKID)
values (:1 , :2 , :3 , :4 , :5 , :6 , :7 , :8 , :9 , :10 , :11 , :12 )

Query 2a (from DB trigger, :B1 is a payload):

SELECT COALESCE(ERROR_DETAILS, ERROR_MESSAGE, FAULT_REASON, SOAP_ERROR) AS ERROR_MESSAGE, ERROR_CODE 
FROM XMLTABLE( '//*:DataHandlerWebServiceException | //*:Fault | //*:PLMDataHandlerError' 
     PASSING XMLTYPE(:B1 )
     COLUMNS ERROR_DETAILS VARCHAR2(256) PATH '*:errorDetails'
            ,ERROR_MESSAGE VARCHAR2(256) PATH '*:errorMessage'
            ,ERROR_CODE VARCHAR2(8) PATH '*:errorCode'
            ,FAULT_REASON VARCHAR2(256) PATH '*:Reason/*:Text'
            ,SOAP_ERROR VARCHAR2(256) PATH '*:COMMON_LOG_MESSAGE/*:LOG_MESSAGE' )

Query 2b (we already know APPEND is ignored here, see Note 1):

INSERT /*+ append */ INTO _response( RESPONSE_SKID, REQUEST_SKID, HAS_FAILED, WAS_TIMEOUT, IS_PROCESSED, SOAP_REQUEST_TIMESTAMP, SOAP_RESPONSE_TIMESTAMP, RESPONSE_HTTP_STATUS, ERROR_MESSAGE, RESPONSE_BODY )
values ( :1 , :2 , :3 , :4 , :5 , :6 , :7 , :8 , :9 , :10 )

How is it possible that INSERTs, to different tables, are blocking the sessions? I was looking into V$ACTIVE_SESSION_HISTORY but don’t find anything yet (I’m not a DBA yet)

Note 1: APPEND hint ignored

networking – Finding out what’s trying to connect to network shares

We have some network shares that are available within the office and remotely via VPN. Often when I open certain pieces of software, Finder will repeatedly tell me that it cannot connect to the server at . If I dismiss these messages, eventually the software will open. The messages also pop up sporadically during the day,

Is there a way of determining why this messages are coming up and which software is looking for what on the network share? I have a suspicion that one of them is Microsoft Teams. As far as I can tell there’s no reason it would need to reach the network drives in order to function.

I’ve tried grep -r <ip address> /Applications/Microsoft Teams.app/Contents to no avail, so I’m a bit stuck.

One thought I had was whether MacOS does some kind of validation on the app itself, and if I was within the office / on the VPN when the app was installed would it be looking for a particular signature for my drives or something.

vpn – How to connect to a wifi network that shuts down connections

Our school’s wifi shuts down after 12 am, and although we are still connected to the network, our connections are closed, and the computer says “no internet”.

However, we can somehow manage to stay connected to the internet even after 12 am if we use a VPN program, but after disconnecting, we cannot connect to the network again even using VPN

How does this shutdown system work and how can I connect to the internet even after it closes all connections?

ubuntu – nginx cant connect to docker php-fpm

I am running nginx on the server and not within a docker container because of troubles with getting a working SSL. I have a docker container set up separately running my-sql and php-fpm. When I have all this running I get file not found and I can’t work out why.

When I run sudo nginx -t it says everything is fine but I still get file not found after I run sudo systemctl restart nginx

My Nginx file:

amazon ec2 – AWS EC2 running Ubuntu 18 VPN will not connect (network manager??)

I am attempting to run a 3rd party VPN (Hotspot Shield) on my EC2 instance running Ubuntu 18.

When i run the the connect command, I get an error for Hotspot Shield client. I have attached the corresponding system log.(enter image description here)(1)

I have tried using two other VPNs (NordVPN and Wireguard) and both cause my ubuntu box to crash when attempting to create a connection.

It strongly appears that the issue is with my EC2 instance, not the client. The instance currently allows all inbound and outbound traffic.

Any insight that could be given is greatly appreciated!!!!!!!!!!!!

16.04 to 20.04 Upgrade Issue: Update Manager Failed to connect to https://changelogs.ubuntu.com/meta-release-lts-development

I am trying to upgrade from Ubuntu 16.04 LTS to 20.04 LTS using the guid at Upgrade Ubuntu desktop. I followed steps 1, 2, and 3, but no option to upgrade appeared. I then typed upgrade-manager -d in my terminal, but got the following error:

Failed to connect to https://changelogs.ubuntu.com/meta-release-lts-development. Check your Internet connection or proxy settings

My internet connection is fine and I am not running a proxy. I searched for similar topics but none of them seemed to resolve the issue. Any help would be appreciated.
