When trying to build kudu in my ec2, I got an error "HTTP/1.1 403 Forbidden". My connection was opened through a proxy. The domain that we are trying to connect to here is "service .gradle.org". This can be accessed through HTTPS. Here the build is run using the gradle wrapper jar (v6.8.3). Here, a 403 Forbidden error of the above type kept appearing. It lookes like the connection is trying to use HTTP instead of HTTPS.
This problem is not occurring when the build is run in an environment without a proxy
Build fail image
as the title says I'm facing the error:
WebSocket connection failure. Due to security constraints in your web
browser, the reason for the failure is not available to this Neo4j
Driver…​
My neo4j DB is running on a Ubuntu Linux machine:
Unbungu 20.04.04 LTS, Release 20.04
Neo4j Community Edition, Version 4.4.8
I can connect to the db via:
http://localhost:7474/browser/
but not under
https://localhost:7473/browser/ or bolt+s://localhost:7687
I already tried multiple "solutions" but none of them work.
Here is what I changed in my config.
dbms.default_listen_address=0.0.0.0
dbms.connectors.default_list_address=0.0.0.0
dbms.connector.bolt.enabled=true
dbms.connector.bolt.address=0.0.0.0:7687
dbms.connector.https.enabled=true
dbms.connector.https.listen_address=0.0.0.0:7473
I also generated SSL certificates:
Bolt SSL configuration
dbms.ssl.policy.bolt.enabled=true
dbms.ssl.policy.bolt.base_directory=certificates/bolt
dbms.ssl.policy.bolt.private_key=private.key
dbms.ssl.policy.bolt.public_certificate=public.crt
dbms.ssl.policy.bolt.client_auth=NONE
Https SSL configuration
dbms.ssl.policy.https.enabled=true
dbms.ssl.policy.https.base_directory=certificates/https
dbms.ssl.policy.https.private_key=private.key
dbms.ssl.policy.https.public_certificate=public.crt
dbms.ssl.policy.https.client_auth=NONE
Any ideas?
*Edit: Typo
I was implementing laravel websockets package in project it is working fine in my local machine but on server first it was giving error of Connection timeout That problem was solved when add TCP port in aws security group but after that it starts giving new error
WebSocket connection to 'ws://52.64.101.38:6001/app/ABCDEF?protocol=7&client=js&version=4.3.1&flash=false' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
Here are errors I am getting in console when try to connect websocket server
I was searching about this error i found this github thread . Which is saying try to bound with 0.0.0.0 but I dont know what does it means,
https://github.com/GeniusesOfSymfony/WebSocketBundle/issues/251
I was also getting this error on local machine but was later resolved when i downgrade package version 1.6
NOTE: I am using ubuntu server aws services
Hi I am trying to build an application handed over to me by another developer.
When I do ionic build android
I get an error:
Could not GET 'https://jcenter.bintray.com/com/android/tools/build/gradle/2.2.1/gradle-2.2.1.pom'.
Connect to 192.168.1.1:808 [/192.168.1.1] failed: Connection timed out: connect
I think the IP address highlighted in bold is the main problem.
My Router Ip address is 192.168.0.1 where can I change this setting so that the gradle files are downloaded properly.
Firefox v39 will no longer connect to my web application over HTTPS. I'm using Spring Boot with embedded Tomcat and I've made sure I'm using the latest version of Boot (v1.2.5). Firefox shows the following error message:
Secure Connection Failed
An error occurred during a connection to [website]. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)
I understand this is to protect against a known vulnerability called Logjam. A solution for Tomcat is provided at weakdh.org.
Spring Boot passes SSL configuration to Tomcat via application.properties and as such I have added server.ssl.ciphers to my application.properties as follows:
server.port=443
server.ssl.key-store=/home/ec2-user/boot.p12
server.ssl.key-store-password=...
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=...
server.ssl.ciphers=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_DHE_DSS_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_SHA,TLS_ECDHE_RSA_WITH_AES_256_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_SHA384,TLS_ECDHE_RSA_WITH_AES_256_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_128_SHA,TLS_DHE_DSS_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_256_SHA256,TLS_DHE_DSS_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_256_SHA
After restarting boot, I notice the following in my log file:
WARN 2674 [main] --- o.a.t.util.net.jsse.JSSESocketFactory : None of the ciphers specified are supported by the SSL engine : TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, ...
Additionally, connecting using Firefox fails with the following message:
Secure Connection Failed
The connection to [website] was interrupted while the page was loading.
And I see the following in my log file:
javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
Unfortunately I'm no encryption expert. Can anyone suggest how to fix this? Do I need to recreate my HTTPS certificate?
The solution was to upgrade server Java on the server from 1.7 to 1.8.
sudo yum remove java-1.7.0-openjdk
sudo yum install java-1.8.0
After this was complete, no other configuration was necessary. Not even modyfing Tomcat as per the advice at weakdh.org.
